Created attachment 64452 [details] New crash information added by DrKonqi kwin (4.6.5 (4.6.5)) on KDE Platform 4.6.5 (4.6.5) using Qt 4.7.3 - What I was doing when the application crashed: startting KDE session - Unusual behavior I noticed: desktop effects are automatically disabled - Custom settings of the application: plasma desktop effects are (were) activated when starting session My GFX card is intel 915, problem occurs when using mesa 7.11-6 from Debian sid. I I downgrade mesa to 7.10-4, problem dissapears. $ dpkg -l | grep mesa ii libgl1-mesa-dri 7.11-6 free implementation of the OpenGL API -- DRI modules ii libgl1-mesa-glx 7.11-6 free implementation of
