It appears to be particular to sandybridge (and perhaps a specific sandybridge variant).
There are no workarounds we can suggest at this time, aside from not using the affected applications or games.
I don't think you'll find much value in doing further testing of xorg-edgers or other branches of mesa until we get word from upstream about possible patches. We'll try to get patched mesas available as soon as practical once a fix exists.
I believe a sufficient amount of analysis has been done, now it's just a matter of waiting on upstream. Knowing the affected games may well help upstream so feel free to test and comment here with names of other games which produce the bug.
Thanks everyone for the testing. It appears this is a known mesa bug upstream - https:/ /bugs.freedeskt op.org/ show_bug. cgi?id= 42538
