Description cdf 2012-01-05 13:59:03 UTC

Application: kwin (4.7.2 (4.7.2))
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
kwin crashes when
	- miniatures in taskbar should be shown
	- miniatures in window switcher are activated and I switch the windows
	- all windows are shown as miniatures at the same time

- Custom settings of the application:
kwin crashes only if effects are activated, especially effects that include miniatures

The crash can be reproduced every time.

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

fglrx driver?
run "kcmshell4 kwincompositing", enter the 3rd tab and set the scale method to "smooth"
you might encounter crashes of the same type with the blur effect, so maybe disable that as well (2nd tab)

alternatively try the radeon driver (xf86-video-ati)
