-- Information about the crash:
- What I was doing when the application crashed:
Present Windows - That Effect Sometimes Crash KWin. Not All The Time, but even
if i change my graphics settings and using default ... it's still the same
problem. I think mostly problem with KWIN it's beacuse of Nvidia Drivers. For
example on Nouveau i don't have any Crash on Kwin. But on nvidia it's normal...
When i open , move , minimalize , show window.... I got KWin crash'es random.
Mostly it's beacuse of "Window" interaction. On nouveau i don't see any
problem...
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
