The i810 driver does not seem involved. I found the same backtrace on the same graphic board in the upstream bugzilla at https://bugs.freedesktop.org/show_bug.cgi?id=9199. There has been no reply so far, but the bug was not against the right component, so... I reassigned it correctly. It would be nice if you could summarize all your conclusions there. Note that I found your last mail pretty hard to understand since there are lots of combinations of modules/envvar/packages involved. It would be nice to explain in a simple way how to reproduce the bug and what works around it. Note that upstream does not really like old versions, so be prepared to have to reproduce with xserver-xorg-core (2:1.2.99.903-1) or xserver-xorg-video-intel (2:1.9.93-1) currently in experimental :) Mesa 6.5.2-3 is fine. > At first OpenGL apps were much slower and had different (but still ugly) > rendering artifacts than before, but after adding Load "dbe" and > Option "XAANoOffscreenPixmaps" (not sure which one helped, sorry) to > xorg.conf the speed went back to normal.

All at the same time? Or any of these lines? Thanks a lot, Brice
