Has anyone else noticed a considerable performance regression in Intel
GM956 graphics after an upgrade from 11.04 to 11.10?

When I drag terminal windows around on my screen the position updates at
what feels like ~6 fps. The compiz workspace sliding animation on
Ctrl+Alt+Left/Right sometimes drops *all* the intermediate frames. I can
sometimes see *tearing* when I'm scrolling text in less in a

I use Unity (and have used in in 11.04).
