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.

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
