** Description changed: - TBD. - --- + See the attached GIF in comment #2. Screen image corruptions are found + with 100% fail rate on TGL-U platforms running kernel >= v5.12-rc1 while + 5.11.0-16-generic kernel from Hirsute has no such problem. + + * mainline v5.12-rc1: affected + * 5.12.0-8-generic: affected + * 5.11.0-16-generic: not affected + + [Steps to reproduce] + Basically this should appear frequently whenever screen image updates. One might also take following steps to trigger it more easily: + 1. Launch several applications/windows + 2. Hold meta key (Windows key) + 3. Press any of the arrow keys quickly + + --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.16 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CasperMD5CheckResult: skip DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2021-04-20 (0 days ago) InstallationMedia: Ubuntu 20.04.2 LTS "Focal Fossa" - Release amd64 (20210204) IwConfig: - lo no wireless extensions. - - enp0s30f4 no wireless extensions. - - enp0s31f6 no wireless extensions. + lo no wireless extensions. + + enp0s30f4 no wireless extensions. + + enp0s31f6 no wireless extensions.
