Comment 44 for bug 681915

I was able to trace this problem on my machine to libgl1-mesa-dri.

Using git bisect I was able to identify and successfully test mesa commit 32218e4cc88f7dedebadffe4a80247decf4498f1 as addressing the problem.

I've rebuilt the mesa package with this patch cherry-picked in ppa:jsjgruber/ppatwo, and this seems sufficient to fix the problem for me.

Would anyone having the problem like to test this fix on their computer?

If so, please be sure to run ppa-purge against xorg-edgers if you have applied that ppa to your system.

Also, please be sure to select the correct ppa. I have another ppa containing another mesa package without this patch!
