• Cartoon Network
• Adult Swim
• Cartoonito

Date	Description	Example
December 16, 1997	The ThunderCats episode Fond Memories encountered substantial technical difficulties. Following the show's custom Toonami intro was just under a minute of blank screen followed by the QTTV Technical Difficulties slide. The slide abruptly cuts to the first act already in process as Mumm-Ra is explaining his plan to trap Lion-O, accompanied by the TV-Y7-FV ratings bug fading in and out. The following establishing shot of Mumm-Ra walking through a cave was then interrupted by a Toonami ThunderCats bumper, followed by the commercial break playing ahead of schedule. After the commercial break ends and a few seconds of blank screen followed by a brief gray screen, the episode starts again, halfway through its title card / credits. The episode then aired properly, albeit with about five seconds of black and gray screens preceding each act of the episode (including the epilogue), and the commercial break being replaced with a Toonami bumper. The screenbug was completely absent for the entirety of the episode.
March 4, 1998	During the premiere of the Robotech episode False Start, the screenbug disappears in the first and last few minutes of the second act.
July 18, 1998	The TV-G rating was accidentally kept on screen during the first commercial break for the Cartoon Theatre premiere of An American Tail (1986).
April 1, 1999	The Cartoon Network screenbug is off-center during the premiere of the ReBoot episode Infected.
June 15, 1999	Following the first act of the Dragon Ball Z episode Elite Fighters of the Universe... the Ginyu Force, over a minute of black screen interspersed with the Technical Difficulties slide was seen instead of going straight to commercial. This was followed by the All Cartoons All the Time CN promo already in progress. After the promo ended, a split second of the Cartoon Library CN promo could be seen, followed by the proper Toonami Dragon Ball Z bumper and commercial break.
June 27, 1999	The premiere of the ToonHeads episode Toro! Toro! had some significant technical difficulties. Instead of airing Bully for Bugs and Senor Droopy, the cartoons The Mice will Play and Sheep Wrecked aired instead. Intermission segments from the previous week's episode, The Nice Mice of Warner Bros. also played. The episode would premiere properly on October 1, 1999.
July 31, 1999	The Cartoon Network screenbug did not return for the majority of the second act during the 3:30pm airing of A Pup Named Scooby Doo. The screenbug eventually did return, but because it happened at the end of the episode, it is only on-screen for less than five seconds.
September 4, 1999	Preceding the Robotech episode Sweet Sixteen is a promo for ReBoot claiming that the show will be airing next. During the episode itself, the ratings bug fades in closer to the left side of the screen than normal, and the Cartoon Network screenbug is off-center.
October 11, 1999	At exactly 3:25am, during the break between today's episodes of The Yogi Bear Show and The Huckleberry Hound Show, during the Shortie City-E-Scape, the Cartoon Network screenbug appeared on-screen for several seconds then disappeared for the rest of the Shortie.
2000	The Cartoon Cartoon Fridays screenbug was mistakenly used during Space Ghost: Coast to Coast.
May 28, 2000	The poll segment for tonight's episode of JBVO labeled that week's poll question as a "Brak or..." question instead of the proper "Should" question (said poll question was about if Shaggy should put on some weight). This was an oversight on the production end of the show, as episodes would be ready for airing a few days before the episode's airdate and thus this error was included on the master tape.
May 27, 2001	During the 8:30pm airing of The Chuck Jones Show, the Robert McKimson short Gone Batty accidentally aired.
June 17, 2001	During the 8:30pm airing of The Chuck Jones Show, the Robert McKimson short Bedevilled Rabbit accidentally aired.
July 2, 2001	During the 1:00am airing of Late Night Black & White, the 2 Stupid Dogs episode Hobo Hounds aired. While the episode was intended to mimic a black and white cartoon, it's unknown if it's airing on the block was intentional or an error. The episode would air during Late Night Black & White again on January 27, 2002.
August 19, 2001	During the 10:00pm airing of The Bob Clampett Show, after the show's "coming up" bumper for Porky's Movie Mystery, tonight's airing of The Tex Avery Show was mistakenly started early, preceded by an Up Next bumper, a commercial break and a Cartoon Network ID. A minute into the first cartoon of tonight's airing (Magical Maestro) the program abruptly cut back to the remainder of The Bob Clampett Show, picking up right where it left off. After the show was over, in order to make up time due to these difficulties, after the Up Next bumper a Technical Difficulties slide and the "Yogi Bear lost his I.D." promo were shown. After that, The Tex Avery Show was restarted again with neither the intro, nor the opening "trivia" bumper. In addition, in between the first and second cartoons, the Technical Difficulties slide reappeared for a few seconds. During the 11:00pm airing of the ToonHeads, in between the two ToonHeads Trivia bumpers, a production slate for the bumper was shown.
September 16, 2001	The version of the Looney Tunes short Tom Turk and Daffy that aired today had no opening credits, nor it wasn't the usual dubbed version they air. In addition, the music video styled banner that was used during airings of The Bugs and Daffy Show in the mid 90s could be seen near the end of the short.
November 17, 2001	An encore edition of Toonami Midnight Run: Special Edition was initially rated TV-G, before switching to a TV-Y7-FV rating a few seconds later. The screenbug also does not appear during the broadcast.
November 30, 2001	The Adult Swim screenbug was used during the first part of the 1:00am airing of Acme Hour.
December 28, 2001	During the 3:00am airing of The Bugs & Daffy Show, the short Kit for Cat had its beginning played in Portuguese. After switching back to English, the screenbug disappeared for the rest of the short.
March 11, 2002	The Adult Swim screenbug was used during the 1:00am airing of The Ruff and Reddy Show.
April 15, 2003	The first half of the Rurouni Kenshin episode First Train Ride: Danger on a Runaway Locomotive! aired instead of the first half of the premiere of the Hamtaro episode Boss, the Cool Ham of the Sea!.
May 12, 2003, June 23, 2003, August 31, 2003	Typically, during Season 2 episodes of Hamtaro, Cartoon Network would replace the second theme song ("H-A-M-T-A-R-O") with the first ("It's Hamtaro Time"). However, during the premieres of The Little Bandits! and Clubhouse Intruders, both openings are used. This also occurs in the airing of Happy Birthday Hamtaro Special!, likely because the master of the special episode began with a title card before cutting to the second theme song, so Cartoon Network simply began with the first instead of replacing the theme song.
May 25, 2003	All cartoons shown during the 7:00pm airing of The Chuck Jones Show were Yosemite Sam cartoons directed by Friz Freleng.
August 12, 2003	The Cartoon Network screenbug did not appear during the first half of today's broadcast of X-Men: Evolution. The bug would return during the second half.
December 5, 2003	During the final act of the 8:00pm Fridays presentation of A Flintstones Christmas Carol, Portuguese audio was erroneously broadcast in the right audio channel, with the original audio broadcasting in the left channel. This was fixed a few minutes afterwards.
July 10, 2004	During the second half of the premiere of the Mobile Suit Gundam SEED episode Stars Falling in Space, the Checkerboard screenbug was used.
April 16, 2005	The premiere of the Dragon Ball GT episode Giru's Checkered Past was supposed to air at 10:30pm; however a repeat of the special recap episode A Grand Problem aired instead.
June 29, 2005	An audio promo advertising more The Grim Adventures of Billy & Mandy mistakenly played during the last 20 seconds of the premiere of the episode The Firebird Sweet (obscuring the episode's audio), when The Life & Times of Juniper Lee was actually the next show.
September 22, 2005	During the 11:00am broadcast of Scooby-Doo and the Monster of Mexico (2003), the menu bumpers incorrectly label the direct-to-video film as a New Scooby Movie. This is done despite the fact that the menu bumper shown during the prior program (Tickle U) had the correct movie labeled as being next.
November 17, 2005	The screenbug was absent during the second segment of today's airing of the ¡Mucha Lucha! episode The Incredible Penny Plutonium until about five minutes into the episode.
January 31, 2006	The intro to G.I. Joe: A Real American Hero replaces Evil Con Carne's intro during the 10:40pm airing of The Cartoon Cartoon Show.
June 3, 2006	The screenbug was absent during the entire first act of the series premiere of Pokémon Chronicles.

November 11, 2006 - June 30, 2007	During the series premiere of .hack//Roots, a banner would pop up claiming that My Gym Partner's a Monkey was airing instead. This was never fixed for the rest of the series' run.
March 24, 2007	During the premiere of the Naruto episode The Third Hokage, Forever... toward the end of the episode, a scene got repeated, then it cut to the credits early before One Piece started five minutes early.
May 19, 2007	The premiere of the Naruto OVA Mission: Protect the Waterfall Village! had a TV-Y7-FV rating, despite the promo and encore airings giving it a TV-PG rating. This is likely due to Cartoon Network forgetting to update the ratings prompt, as it aired in the timeslot normally held by TV-Y7-FV shows.
August 24, 2007	The Adult Swim screenbug was accidentally shown during the first three minutes of the 10:30pm airing of Codename: Kids Next Door before switching to the regular screenbug.
August 25, 2007	The Adult Swim screenbug was accidentally shown during the last few minutes during the premiere of the One Piece episode Wreckers Reef.
April 10, 2008	Today's new episode of My Gym Partner's a Monkey erroneously used the regular screenbug instead of the "New Episode" screenbug. This was likely because it was a last minute change, as Camp Lazlo was originally going to air in that slot.
October 18, 2008	There was no "New Episode" banner during the 10:30pm premiere episode of Naruto.
November 27, 2008	During the premiere of the My Gym Partner's a Monkey episode A Thanksgiving Carol, The "NEW EPISODE" indicator was not used.
August 29, 2009	Various technical issues happened during the premiere of the Yu-Gi-Oh! 5D's episode The Profiler. After returning from a commercial break, the TV-Y7-FV rating bug appeared on a black screen for several seconds. A minute later, the program was heavily pixelated, with the Cartoon Network bug intact. The episode was abruptly interrupted by promos, causing the ending of the episode to be cut off. Due to the error, Ed, Edd n Eddy began airing four minutes ahead of schedule.
October 3, 2009	The "New Episode" bug did not appear on today's new episode of Yu-Gi-Oh! 5D's.
October 18, 2009	Various issues occurred on the west feed during the last half-hour of the premiere of Casper: A Spirited Beginning. These included inadvertant airings of outdated Har Har Tharsdays promos and promos for the already-aired premiere of Star Wars: The Clone Wars being shown, interspersed with the Picket Fence Technical Difficulties slide and a still image of the Cartoon Network logo taking up the majority of a black screen. This did not occur on the east feed.
November 8, 2009	During the "Big Picture Show Weekend" marathon, the episodes of Ed, Edd n Eddy scheduled for 6:30pm, Pick an Ed and Cool Hand Ed aired without the marathon screenbug.
November 15, 2009	During the Looney Tunes marathon, the 6:00-7:00pm block aired without the marathon screenbug.

May 24, 2010	The "NEW EPISODE" banner did not appear during that night's new Adventure Time.
August 7, 2010	All episodes in the Chowder Grows Up Pop-Up Marathon had PAL speedup. This was mainly due to the network using the Australian feed's pop-up masters, which were designed for the PAL format.

November 12, 2011, December 17, 2011	Typically, episodes of Bakugan Battle Brawlers have the screenbug in the top right corner of the screen, presumably to avoid obscuring the scores. However, the "Up Next" banner, which at the time was an extension of the lower right hand corner screenbug, appeared at the bottom of the screen twice during the premieres of the episodes Countdown to Doomsday and Evil Evolution, with the words "Cartoon Network" not visible on the logo, causing the episodes to temporarily have two screenbugs.

November 12, 2012	As soon as the premiere of the Regular Show episode "Bald Spot" started, the SD feed went to a blank screen for an unknown length of time. In addition, the SD feed was being simulcast on Cartoon Network HD in place of the episode being played directly.

May 7, 2022

February 10, 2023	The screenbug disappeared during the second half of the 7:00pm airing of the Scooby-Doo and Guess Who? episode Now You Sia, Now You Don't!. Despite this, a banner promoting the Teen Titans Go! Slam Dunk Special still appeared, causing the bug to jarringly cut in.

March 26, 2023	The 3:49pm airing of the Teen Titans Go! episode Real Art used the TV-Y7-FV rating instead of its normal TV-PG rating. The episodes of the show that aired during 10am-12pm also had the Marathon screenbug.

May 4, 2023	The screenbug disappeared during the second half of the Foster's Home for Imaginary Friends episode Challenge of the Super Friends. When it disappeared seemed to be dependent on which feed it was on.
May 14, 2023	The Adult Swim screenbug shows up during that night's Futurama episodes, airing as part of ACME Night during the bugless purgatory hour.
May 20, 2023	Cartoonito's split screen credits template was shown at the end of the Teen Titans Go! episode Toilet Water.
June 2, 2023, June 9, 2023, June 16, 2023	The TV-Y rating bug was shown at the beginning of the first and second act of the The Looney Tunes Show episode Muh-Muh-Muh-Murder, as opposed to the episode's actual TV-PG rating. This error would persist for the re-runs of episodes Point, Laser, Point and Bobcats on Three!.
June 4, 2023	The Tom and Jerry Tales episode(s) More Powers to You / Catch Me Though You Can't / Power Tom and Destruction Junction / Battle of the Power Tools / Jackhammered Cat from 8:00-9:00am used Cartoonito's split screen credits. The Tom and Jerry Kids shorts Catch as Cat Can and Fathers' Day at 10:30am and 11:30am used the TV-Y7 ratings bug, as opposed the usual TV-G, which their paired episodes still used. The Tom and Jerry Show shorts Say Cheese, Dinner is Swerved, Don't Cut the Cheese, The Paper Airplane Chase, Cheesy Ball Run, and Calamari Jerry used the "New" screenbug, when all of those episodes had aired on Cartoon Network before. The episode Calamari Jerry used a TV-Y rating as opposed to the usual TV-PG rating. Despite never airing on Cartoon Network before this, the Justice League: Crisis on Two Earths (2010) did not use the premiere bug. Also, it used the old (Helvetica Bold with white background) ratings bug and ended with Adult Swim's "river" style split screen credits.
June 11, 2023	The airings of the Uncle Grandpa episodes Belly Bros, Afraid of the Dark, Funny Face and Driver's Test from 8:00-9:00am used the Cartoonito split screen credits. The 6:00pm ACME Night airing of the Batman 1989 film used Adult Swim's "Dirt Road" split screen credits.

June 28, 2023-June 30, 2023	The Lamput shorts Orange Rose and Orange Umbrella airing after the Craig of the Creek episode The Ice Pop Trio were advertised as new on the "up next" banner, despite already premiering months prior. A similar situation occurred during the Craig of the Creek episodes The Last Game of Summer on June 29th and Afterschool Snackdown on June 30th.
July 9, 2023	The premiere of All-Star Superman (2011) used the old Helvetica ratings bug, used Adult Swim "River" split screen credits, and during the first act, there was no screenbug.
July 13, 2023	During the airings of The Looney Tunes Show episodes The Grand Old Duck of York and The Shelf, the bumpers for classic Looney Tunes were used.
July 23, 2023	Today's new episodes of Summer Camp Island erroneously used the regular screenbug instead of the "NEW" screenbug. This was likely because of scheduling changes shifting the premieres of the episodes The Babies Chapter 1: Breakfast Errands, The Babies Chapter 2: Teacup Giant and The Babies Chapter 3: Lem Is Nothing to Sunday rather than the usual weekday slot.
August 28, 2023	After the 4:45pm airing of The Amazing World of Gumball episode The BFFs, an Up Next bumper for The Amazing World of Gumball played, despite Cartoon Network signing off at 5:00pm on this day.
September 23, 2023	The repeat of the Teen Titans Go! episode Utility Belt at 9:45am used the New screenbug and had the "new" bumpers before it. This is very likely due to it and the early premiere of Intro replacing the WB 100th Anniversary episode at the last minute.
September 25, 2023	Due to the legacy Turner networks, including Cartoon Network, migrating to Discovery's cloud-based playout, numerous errors occurred during the transition. See this page for more info.
September 26, 2023 - September 27, 2023	Continuing from the Discovery migration, the classic Looney Tunes bumper still played before and during the Baby Looney Tunes episode(s) A Bully for Bugs / The Wheel Deal and Oh Brother, Warehouse Art Thou? / Flu the Coop at 9:00am and 9:30am respectively on the 26th. On the 27th, the Teen Titans bumper played before the 2:00pm showing of the Teen Titans Go! episode Booby Trap House.
October 9, 2023	At around 6:15am, during an episode of The Amazing World of Gumball, the screenbug disappears, but comes back at around 7:15am.
October 29, 2023	The Up Next bumper for The Looney Tunes Show was accidentally shown before the 12:30pm airing of the Tiny Toons Looniversity episode Tears of a Clone.
November 18, 2023	The "New" screenbug was used during the 9:45am airing of the Teen Titans Go! episode Thanksgiving despite it first airing in 2014.
December 10, 2023	The ratings bug and screenbug appeared in the credits of the 3:00pm airing of The Amazing World of Gumball episode Christmas.
December 24, 2023	Again, the screenbug and ratings bug appeared in the credits for The Amazing World of Gumball episode Christmas that was aired at 1:30pm. This also happened during the credits of the Regular Show episode Snow Tubing that was aired at 4:45pm.

May 27, 2024	Today's new episode of Jessica's Big Little World aired without the "New" screenbug.
June 9, 2024, July 7, 2024	Both airings of The Scooby-Doo Show on June 9, 2024 were preceded by the Up Next bumper for Scooby-Doo and Guess Who?. Similar to the error affecting Baby Looney Tunes the preceding September, this was likely because a Prism bumper for the show that actually came on didn’t exist yet. The error was fixed once the show aired again on June 16, 2024, only to return (albeit only during the second half-hour broadcast of the series that day instead of both airings) on July 7, 2024.

Date	Description	Example
September 2, 2001 - September 10, 2001	Adult Swim programming would have the ratings bug linger throughout the episode. This might have been done deliberately to indicate that these programs were not for kids.

November 29, 2001	Cartoon Network's screenbug was accidentally used between 10:30pm to 11:15pm.

October 26, 2003	The Big O's series finale The Show Must Go On was originally scheduled to premiere that night, but a rerun of the episode Stripes was accidentally aired in its place. It would instead premiere on November 2, 2003. Said program change also delayed the American television premiere of the Family Guy episode When You Wish Upon a Weinstein by a week.
April 19, 2004	During the first segment of the 1:30am airing of The Popeye Show, the TV-PG parental guidelines rating (most likely for the following program, the Futurama episode Mars University) accidentally popped in for a few seconds.
September 25, 2004	During the premiere of The Venture Brothers episode Mid-Life Chrysalis the Cartoon Network screenbug appeared for a few seconds. It then switched to the correct screenbug for the rest of the episode.

January 21, 2007	During the premiere of the Bleach episode Reclaim! The Power of the Shinigami! shortly after the show returns from the commercial break, the picture freaks out in a way similar to a satellite glitch. However, the [as] bug remains intact indicating this is a problem with the master for the episode itself.
June 20, 2011	During that night's airing of the Family Guy episode Let's Go to the Hop after the commercial break, the rating of the episode changed from TV-14-SV at the start of the program to TV-PG-D when the show returned from commercials.
August 24, 2011	The rating bug appears twice during the opening of that night's airing of the Family Guy episode Road to Germany, making the closed captions bug not appear during that night's broadcast.

January 5, 2017	Somewhat similar to the above error in an inverse way, the Adult Swim bug disappeared during the second half of the 4:45am airing of the Space Ghost Coast to Coast episode Sleeper, and would not return for the remainder of the episode.
March 7, 2017	During the second half of the 12:30am airing of The Boondocks, the TV-Y rating bug is accidentally shown.
April 15, 2017 - April 16, 2017	The Cartoon Network logo appeared during the opening for tonight's episode of Dragon Ball Super. Said occurrence of both screenbugs appearing at the same time would continue throughout the following day on both networks, eventually stopping on a rerun of The Brak Show a day after.
May 6, 2017	The 10:00pm airing of the Samurai Jack finale used a TV-PG-V rating instead of its original TV-14-V rating.
March 17, 2019	Six minutes into the premiere of the Sword Art Online: Alicization episode Project Alicization, the show froze on one frame. The frame remained like that for a few minutes before the show cut to a commercial break, but when returning from said break, the freeze frame from the first act persisted. Because of this, the Megalobox episode Leap Over the Edge of Death started early, then aired in full in its normal slot.
December 20, 2020	A promo before the premiere of Wonder Woman: Bloodlines erroneously states that the regular Toonami lineup would return the week after, when a Cowboy Bebop marathon was already scheduled for that day. This may be because the Cowboy Bebop marathon was originally scheduled to air November 29, 2020 instead.

Additionally, an E/I bug temporarily appeared in the bottom right corner of the screen. Notably, this E/I bug was used back in the late 1990s to identify an E/I compliant program on Turner's channels, which in Cartoon Network's case, was used during Big Bag and Small World.
December 12, 2021	The Yashahime: Princess Half-Demon season 1 finale, Sesshomaru's Daughter, was supposed to air at 1:30am, but was accidentally replaced at the last minute with a rerun of Secret of the Rainbow Pearls.

June 26, 2022	During the first half of the Naruto: Shippuden episode One Worthy as a Leader, the TV-PG rating bug remained on screen the entire time until it cut for commercial break. Once the episode resumed after the break, the smaller version of the rating bug disappeared as intended.
December 25, 2022	The screenbug disappeared during the Adult Swim Yule Log.
June 4, 2023 - July 23, 2023	During the midnight airing of the Unicorn: Warriors Eternal episode The Mystery of Secrets on June 4, the Adult Swim: Stream On Max bug was visible for the first act, but the regular bug returned during the second act. This error also occurred in the 11:30pm airing of the American Dad! episode Camp Refoogee on June 10. In the Unicorn: Warriors Eternal episode The Heart of Kings that aired immediately after, the regular screenbug was used in the first act, then the Max bug in the second, then the regular in the third. This continued into the American Dad! episodes Saturday nights at 11:30pm and Unicorn: Warriors Eternal and My Adventures with Superman episodes Sundays at midnight.
July 16, 2023	The Dr. Stone episode Treasure Box was supposed to air, but was accidentally skipped and Ray of Despair, Ray of Hope aired instead.
