Bug Description
When I start compiz (latest lp:compiz-core), moving windows with the "move" plugin doesn't follow the mouse very well. Windows jump erratically and mostly move only about 20% of the distance the mouse pointer moves.
Then after a few seconds of switching windows, it fixes itself. The move plugin honours the mouse movements correctly thereafter.

Indeed, this is the geometry race condition that I was trying to fix earlier. Core does its best to handle the inherent contradiction between synchronous and asynchronous geometry updates, although in some cases this fails (race condition).
I think the best way to fix this, as I have mentioned earlier is to force all plugins to use the asynchronous path. Though ... we are running out of time for this.
