Comment 10 for bug 450901

The fix has also made it into mesa_7_6_branch upstream. This is being tracked in https://launchpad.net/~ubuntu-x-swat/+archive/x-updates which may be a more stable workaround than running the 7.7 branch from xorg-edgers. This should also make it easier to bisect if anybody wants, but I'm not sure a patch will make it into Karmic at this point. Should anyone want to do it, I can recommend the detailed blog post that Michael Strecke has written: http://tuxpool.blogspot.com/2009/12/bisecting-mesa-bug-446632.html .
