If I have two monitors, side by side, then the Unity bar will interfere with mouse movement. I set the unity bar to only display if I move the mouse to the top left corner of the screen, but the mouse still pauses momentarily when I move the mouse from the right display to the left display. The place it pauses, is exactly on the left border of the right screen.

That did the trick, thanks. Ah, there is still a small delay the, to give unity the option to come out of autohide, but the pain is gone! – Jack Jul 17 '12 at 10:05
