Can you bisect to see what change broke it?
Comment 2 aceman 2010-09-30 11:18:35 UTC 
It also does not happen on 7.9 with software rendering.
I could try to bisect by date, but I don't know where to download the nightly snapshots.
Comment 3 aceman 2011-01-12 12:27:53 UTC 
After trying bisecting mesa 7.9 and finally returning to the official snapshot, the problem solved itself. Closing for now.
