With unity+compiz from the PPA on sandy bridge graphics, I have so far encountered one instance of degradation (but it's nowhere near as bad as before).
The degradation is that I see some tearing when moving a window around (which no longer happens immediately after login) and occasionally the window 'freezes' for a second before jumping over to where the mouse now is.
glxspheres is doing something similar: it reported 59, 59, 42, 59, 59, 42, 59, 59, 42,... ie every few seconds it was stuttering and losing framerate, then recovering.
A minute later I still see the tearing but glxspheres seems to have totally recovered. The 'freeze' when moving a window around is also much improved.
