Update: After extensively screwing around with compiz config options and then restarting X, the problem is magically gone. The weird thing is, I had restored all of the settings to their original settings. Afraid to reboot now.

Update: Disabling window decoration and moving the window with ALT-click removes the extreme lag, but it is still choppy.

This happens to me too, exactly the same as glazs' video. Disabling vblank sync does not fix it, although it does fix other compiz effects (e.g., expo).

Oddly, toggling "enhanced zoom desktop" off and then on again caused a visible reset of the unity border features, and this fixed the extreme window choppiness for about a minute, bringing the window redraw rate during dragging up to about 10fps. An improvement, but still nowhere near the ~60fps I had with Ubuntu 10.10.
