--- Comment #5 from Michel Dänzer michel@daenzer.net 2010-05-14 07:31:59 PDT --- Quite a few more extensions are available with direct rendering, e.g. GLX_SGI_video_sync. Maybe there's a problem with one of those. Might be interesting to, with direct rendering:

* If the maniadrive process hogs the CPU: Get a profile with sysprof or oprofile. * Otherwise: Interrupt execution at regular intervals in gdb and see if it's in a particular place most of the time.
