firefox picture rendering problems

Hi all,
i've weird problem. When i'm browsing sites using firefox, all picture are really crapy (ie. imagine small picture 20x20 zoomed 20x) and when i'm scrolling firefox down with down arrow key or with mouse, there are displayed only some colour areas.. Have you anybody noticed the same problem? When browsing using opera everything is ok..
Arch is up-to-date, firefox v 3.0.3 Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.3) Gecko/2008100320 GranParadiso/3.0.3

thanks in advance,

Re: firefox picture rendering problems

Please attach your xorg.conf, this is a bug in xorg that can only be triggered by turning on some option that should no longer be used.

Re: firefox picture rendering problems

Try adding these to the device section of your videocard:

Option "XAANoOffscreenPixmaps" "true"
Option "XAAOffscreenPixmaps" "false"

This should be the default however, don't know why it isn't in your situation. Which xorg-server do you use?

Edit:
OK, makes sense. Probably 1.5.2 from testing. We removed most patches from 1.5 when we pushed it to testing, but this one is still needed. Upstream has this option enabled by default.

Re: firefox picture rendering problems

Both Fedora and Ubuntu don't include this patch anymore because it was fixed some other way it seems. I see you're forcing XAA as acceleration method in xorg.conf, while EXA is the default for xorg 7.4.
