--- Comment #12 from Marek Olšák maraeo@gmail.com 2010-12-25 13:10:19 PST --- Could you possibly bring this issue and the patch to the mesa-dev mailing list? I can't comment on something I can't reproduce and this seems to be quite special. Maybe the Mesa maintainers will know what is going on. I don't think that patch is going to be accepted, but at least it's a good starting point.
