Note to self, and Compiz developers...

I managed to fix this bug by hacking the CompTimer source priority;
lowering the priority to around "IDLE" level. This allows compiz time to
process all pending X events (such as mouse motion) before rendering
each frame. Unfortunately it's not a fix I can recommend right now
because it created bugs with full-screen painting modes.

I think an alternative fix might be possible by optimizing the compiz
"move" plugin to reduce the overhead associated with handling so many
motion events. Especially when there are multiple such events pending
and you know the newest one is the only one that's really important.
