E.g. set > num_back = 1 in the else case. Ok, I've built mesa with that parameter changed and installed, same behavior. I've cloned just "git://anongit.freedesktop.org/git/mesa/mesa" , it should be enough.

I will try to investiate more, but I'm really not sure where to look.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
