Description Alex SchiFFer 2010-10-19 14:38:26 UTC
Application: kwin (4.5.1 (KDE 4.5.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: was trying to swith desktops using the screen corner points

- Unusual behavior I noticed: sometimes windows from the different desktops mixed in one (from 3d and 4th to 3d or 4th :)), but didn't response and for a while became to work properly

- Custom settings of the application: my g-card is onboard, opengl source for graphical effects was failing every reboot (effects swithced themselves off), so i use xrender - slower, but self-restorable after the halt and almost never hanged the system.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KWin (kwin), signal: Aborted
