-- Information about the crash:
- What I was doing when the application crash:
Kwin crashes when aplying any change which refers to OpenGL. It can be a change in global effects settings, turning on/off a compiz effect, changing an advanced effects settings, change in decorations, wallpaper... Crash apperas only when using OpenGL, when I use XRender works ok, but doesn't look as good and smooth.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
