Comment 126 for bug 296167

Well I've came up with a decent workaround (at least i think so), you can force the mouse and xserver back in sync by using a simple command from the xautomation package. simply forcing the mouse pos to the origin of the desktop forces them back in sync.

I've written up a short guide http://www.gen-x-design.com/archives/workaround-for-ubuntu-810-mouse-bug/ that shows the steps and how to wire it into a single keypress under gnome. This means when the mouse locks the fix is simply hitting a single key combo.

This has moved the problem to a minor annoyance for me.

it should be easy enough, to adapt this to other setups.
