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.

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.
