--- Comment #182 from Michel Dänzer michel@daenzer.net --- (In reply to Maximilian Böhm from comment #179)
Just want to remind you that there is a Mesa connection somehow.
I've seen that mentioned before, but the answer is always the same: Please bisect Mesa.

I know it's early to say this but 3.18 rc2 solved this bug for me.
Can you bisect which commit in 3.18-rc2 fixed it for you?
