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 |

I have a radeon mobility 9700 64MB ram r300 I don't have compiz enabled. Some 2D apps are a bit slow. I will give you examples: - a maximized terminal, with "man bash" open, when scrolling down fast (lots of cpu usage and huggy scrolling) - other apps in the terminal, especially if maximized, when scrolling - firefox, when viewing flash (flashplugin-nonfree) big animations (lots of cpu usage, very slow animations, in some case) example: http://notebookitalia.it/ricognizione-notebook-santa-rosa-centrino-duo-centrino-pro.html click on the CPUs image to start the animation - evolution, when scrolling (up and) down fast between the email, the cpu goes to 100%, and the scrolling is slowed down a bit - evince, when scrolling a pdf everything gets blocked until the image is drawn. scrolling is terribly slow my distribution: ubuntu gutsy my packages: compiz 0.5.2-0ubuntu3 xserver-xorg-video-ati 6.6.193-1ubuntu1 xserver-xorg 7.2-5ubuntu6 xserver-xorg-core 1.3.0.0.dfsg-6ubuntu3 mesa 7.0.1-1ubuntu1 libdrm2 2.3.0-4ubuntu1 My xorg.conf is clean
