So far, mesa 8 is better. I could use it even if often it crashes during kart races. With mesa 9, races can't even start. Further backtraces and system info available at http://bugs.debian.org/691292 Bug describes how it behaves on current Debian wheezy, Mesa 8. -- You are receiving this mail because: You are the assignee for the bug.
