Hi,

so did the upgrade, today's sid, but what should I say... its still the same. 

Did some re-investigation. Running plain xfce at 800x480 gives nice image, no distortion. At once when I start an opengl application, flickering of the whole screen begins, not just the window containing the opengl application. The more opengl "activity" the more distortions. Glitches mostly stop when exiting opengl application.
I'm out of ideas.

Any way I can help debugging?

Tobi
