It is indeed fixed now. After booting into the new kernel and

The DRI settings workaround eliminates the random stops.
But I have a feeling that it ran more smoothly in Intrepid, now it looks
like ~2-4 fps with zoom taking about 2 seconds, if I have more than

For me the problem usually appears only after a Suspend and Resume.

For the record, I can perfectly reproduce this after suspend when using
EXA (GMA945).
I have used UXA since today, and with that suspend/resume with compiz
works fine, i. e. this bug doesn't hit me with UXA.
As requested by Steve, I'll put this onto the release radar.
