I just managed to resolve 2 problems: the evince one and the slow flash animation one just adding Option "XAANoOffscreenPixmaps" why is this option needed? I have to correct myself: the animation in http://notebookitalia.it/ricognizione-notebook-santa-rosa-centrino-duo-centrino-pro.html is not flash! I really don't know which type is.

I really don't know which type is. > Hi, I've had the same problem and I've described it here: http://vrodic.blogspot.com/2008/01/firefoxmozilla-performance-under.html Basically looks like software rendering fallback overhead. A lot of it could be due to missing RENDER acceleration. Confirmed on opensuse 10.3 (xorg 7.2 with fixes up to october 2007) with a radeon 9200SE (rv280). this bug is actually also valid for the at least one additional driver: intel Use Option "XAANoOffscreenPixmaps" "true" (and add Option "AccelMethod" "XAA" for newer drivers, since the EXA performance is also really bad for the intel driver). I've changed the bug 12069 title, and the component and reassigned the bug to the default assignee, since this is clearly a wider XAA problem. fixed in EXA with migration heutistic = greedy I've thrown away XAA |
