Description illumilore 2013-09-09 22:01:17 UTC

When resuming from a suspending computer with kubuntu 13.04 x64 and nvidia gt440, there will be graphical glitches shown on screen. Various parts of the screen will be stretched or jumbled. Ctrl+Alt+f1 and then killall kwin, then back to f7 and restarting kwin there fixes the issue, indicating that it is a kwin issue.

Reproducible: Sometimes

This can't be duplicate. Kwin does not crash with open gl things closing.

Comment 4 Thomas Lübking 2013-09-28 09:27:59 UTC

The term "crash" in the dupe is misleading and just used to describe the effect and not like "segfaults"

Comment #41 there stresses the "only on resume from STR" aspect.

All ppl. affected use the nvidia blob - and since a while i get severe issues when changing to VT1 after a resume as well (by severe i mean that the framebuffer konsole gets inaccessible and after logging out from KDE, the KDM greeter only shows the wallpaper)

"On closing OpenGL" translated to "minecraft" and comment #33 constrained the problem to "wake up from str" for kwin >= 4.10.97
