Hi all,

I met the following problem with Kubuntu Hardy Heron KDE4 edition, updated to KDE 4.1.0.

When I play a game like native linux game "UrbanTerror" kwin crashes directly after quitting the game (game windows closes when coming back to Desktop) with the following message:

"A Fatal Error Occurred
The application KWin (kwin) crashed and caused the signal 6 (SIGABRT).
Please help us improve the software you use by filing a report at http://bugs.kde.org. Useful details include how to reproduce the error, documents that were loaded, etc."

It happens not every time, but now it already happened two times.

The bug report from KDE is attached:

---------------
if this was already reported sorry for wasting your time...

I checked the problem and was able to reproduce it with any game I run. I think it must have something to do related with graphics.


I filed a bug report here : http://bugs.kde.org/show_bug.cgi?id=167798
Bug 167798: kwin crashes after quit game "UrbanTerror"

can someone confirm this behaviour or somebody knows a fix?

Thank you and best regards,
