I see this problem in compiz *without* using xserver-xgl, but rather with GLX capabilities in the open source ATI video driver, so the bug may lie elsewhere. Indeed, I see the problem even when I just enable System->Preferences->Appearance->Visual Effects->Normal (i.e. no compiz at all). The artifacts are especially bad when slowing dragging windows up or down. I'm attaching a screenshot.
