Description Lukas 2011-03-27 19:16:39 UTC

Application: kwin (4.6.1 (4.6.1))
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.37.1-1.2-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I was watching videos from http://www.youtube.com/user/virtualstrategist#p/u/3/AdXt8BfiGJg (haven't noticed similar behavious with any other video) in full screen. After killing X and playing same video - problem repeated. 

 when KWin became mad. 

- Unusual behavior I noticed:

Clicking any button - close to impossible. 
It looked like there is some half dead (kwin didn't reconize it) transparent window on top, forcing KWin to fight for the screen. Alt+tab was losing and again - recovering focus ten times per second so  was realy flickering and unusable.


System: Thinkpad T410 i5-520M with Intel graphics. Flash 64bit

The crash can be reproduced some of the time.

-- Backtrace:

New crash information added by DrKonqi

kwin (4.6.00 (4.6.0) "release 6") on KDE Platform 4.6.00 (4.6.0) "release 6" using Qt 4.7.1

- What I was doing when the application crashed: Watching a flash trailer for the movie SALT on the streaming service Voddler.

- Unusual behavior I noticed: Window flickering and especially flash elements flickering. The flash movie fullscreens behind the browser its running in. To actually view the video I had have to minimize the browser window.
