https://bugs.freedesktop.org/show_bug.cgi?id=91278 --- Comment #13 from Mathias Tillman --- Sorry for triple posting, but I have some more info that may or may not be useful. When enabling verbose output from glretrace, I can see that the next to last operation before a hang is always glBindBuffer (I've run it 10 times) even though the rest of the output is very different. This, however, only happens when double buffer visuals is enabled, if I disable it using --sb the output is the same as above, ending with glXSwapBuffers. Not sure if this is a coincidence or not, but it seemed interesting to me. -- You are receiving this mail because: You are the assignee for the bug.
