This is fixed with the AMD Catalyst/fglrx 9.01 release stream (aka Catalyst 12.11), among other 2D improvements.

You you hover over some links, like the ones on engadget.com on the right (recent reviews), it stutters A LOT. When you go to about:flags and check "disable GPU Vsync" it runs smoothly and perfectly fine like it did with Compiz 0.9.7.x. Also while hovering/moving over links (with Vsync on/off), CPU usage goes up till 60% on my quadcore, but that's another story and has always been like that). I know there's one more Vsync related fix coming with the final compiz 0.9.8.4 release, but I think I've read it only matters for nVidia.
