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.
