I'm only fixing the exact problem described in the Bug Description. So
the fix will only work for you if the workaround described at the top
works for you.

Of course, if the workaround works for you then you could always have
kept Unity 3D. Just turn off Sync To VBlank in CompizConfig Settings
Manager and turn on Tear Free Desktop in ATI Catalyst Control Center.

Actually I found the workaround still has slightly better performance
than the fix. This is because even with the fix, compiz has to wait for
Vblank. But the workaround uses GPU/driver features to do the same thing
more efficiently.
