Thanks, but unfortunately the sysprof callgraphs are pretty much useless on 64 bit. That said, your mention of iceweasel reminds me of https://bugs.freedesktop.org/show_bug.cgi?id=47266 , which apart from the visual corruption also involves degraded performance due to many more software rendering fallbacks. If downgrading libcairo2 to 1.10.2 works around the problem, that's probably the best workaround for now until we get a better handle on the above. Otherwise, Option "NoAccel" might be feasible if you don't need OpenGL or XVideo acceleration. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Debian, X and DRI developer -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
