Description Darin McBride 2010-07-22 17:01:02 UTC 
This is pretty consistent.  I compiled the latest mesa from git, and still get this.  Note that I had compositing working fine a few days ago, so this appears to be some sort of regression.

Application: KWin (kwin), signal: Segmentation fault

Comment 1 Marek Olšák 2011-03-02 06:38:30 UTC 
It seems to be fixed now (r300g).

Feel free to reopen if think otherwise. Also, testing a non-rc version of kwin would be more useful.
