           Summary: Nouveau 3D driver: nv50_pc_emit.c:863 assertion error
                    kills Compiz
           Product: Mesa
           Version: 7.10
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: sense at ubuntu.com


When you use the experimental Gallium3D driver of Nouveau to enable DRI, Compiz
will actually try to run, but it will be abort because of the following
assertion error:
"compiz: nv50_pc_emit.c:863: emit_flop: Assertion `STYPE(i, 0) == 0x09'
failed."

It seems that this only happens with PCI-E cards that have the NV50 chip.
