This is dri2 problem that I have reported to bugzilla some days ago. It
seems like clipping regions are set incorrectly. But I don't know about
performance side because I hve had only 200 fps in gears with agp mode and
800 fps with pci mode. (2500-3000 in dri1 mode) But atleast performance
haven't regressed for me in dri2..
