KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

kwin crashes if opengl is choosed as renderer in system settings.

The crash can be reproduced every time.

Please provide hardware/driver for bug statistics.
Thanks

-> If you use an AMD/ATi chip and fglrx (catalyst)?

- try the radeon driver (xf86-video-ati/ati-dri)
- try fglrx with enforced direct rendering (late versions have been reported to be reliable) "KWIN_DIRECT_GL=1 kwin --replace &"
- remain staying away from the ARB shader using code (disable blur effect and set the scale method to smooth and esp. NOT accurate)
- ensure that this issue in fglrx is not caused by it's setup demands (afaik one has to run some script after un/installing it)
