A potential workaround to either bug is to reduce the sample rate of
your mouse to about 2x the refresh rate of your monitor. It's normally
about 16x by default so compiz and xorg have to process up to 16 window
movements every screen refresh. Obviously you can only every see 1
movement per refresh
Before adding ppa:vanvugt/compiz, I had lagging type 1 as well as type 2.
windows move smoothly for some time when I restarted unity, but after some time
window movement always got really jerky.
applying your fix basicly eliminates the lags most of the time, but jerkyness

Also, I suspect there are two very different bugs here, and maybe we
need to treat them separately...
1. Moving windows lagging behind the mouse pointer by a few frames; a
few milliseconds.
2. Moving windows lagging behind the mouse pointer by 1-2 seconds;
windows appear to freeze when dragging.
Could you please report the version of compiz you have installed and
provide a video of the lag still happening?

Note to self, and Compiz developers...

Nick, When you say "laggy", do you mean:
(a) the windows appear to stutter in a jerky way?; or
(b) tearing is visible (horizontal lines where moving windows look sheared)?; or
(c) that they smoothly lag a long way behind the mouse pointer?; or
