I am not the reporter of the bug, but the problem is still present for me. If I uncheck compiz sync to vblank windows move slow.
The problem is that with sync to vblank enabled windows move smooth but fullscreen updates are limited to 30FPS for me. Without sync to vblank in compiz I get my 60FPS like expected. The difference is very noticeable, try <super>+s with sync to vblank enabled and disabled.
