Yes, it does. Only restarting computer or running "DISPLAY=:0 kwin_x11 --replace" (generally restarting kwin) does help.

(See my screenshot URL above) Yes, exactly, with one exception: Windows without window decorations (e.g. Steam's windows) do not have the glitching obviously, since they aren't affected by any decoration at all. (In reply to Thomas Lübking from comment #11) > you can "kstart5 --fullscreen glxgears" I tried this and it does not suspend the compositor and does not cause the issue. > And depending on your findings (and since you're on gentoo ;-): > https://github.com/luebking/starfield > Even if I'm not using Gentoo (but Arch) I'll report my findings ;-): This does not suspend the compositor either and therefore no issue, too. I tried running another fullscreen application (game Warzone2100) but the same behavior seems to apply. One problem I've encountered with Warzone is, that I can't switch windows when running fullscreen (information: warzone uses SDL fullscreen) which means I can only guess if compositing has been disabled or not. Now I'm asking myself why those programs haven't caused the compositing to be disabled? The program which caused compositing to be disabled (and therefore led to distorted window decorations) was Counter Strike: Global Offensive. -- You are receiving this mail because: You are watching all bug changes.
