Yes, also with 5.7 the corruption appears if I start /usr/bin/konsole or /usr/bin/dolphin (and I guess it will be apparent with more applications, if you want I could test some more). Although, I have no trouble using chromium or steam, playing all sorts of games. As you can see if you look through the thread, it might be reason to believe that plasmashell itself might be the culprit sending the data that corrupts the screen. - Mads On 2016-07-11 23:42, Marek Olšák wrote: > Can you see any corruption or is there just the message in dmesg?
