Application: kwin (4.5.4 (KDE 4.5.4) "release 3")
KDE Platform Version: 4.5.4 (KDE 4.5.4) "release 3"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.5-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
I changed the Texture filter to trilinear in system settings->desktop and applied the settings. It happens with it all the time. If it is the driver maybe there is potential of cooperation in the teams?

The crash can be reproduced every time.

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