With APZ turned on, when I connect to my Apple TV, mouse event calculations in the entire window starts to break which means that you cannot use the mouse for anything.  Based on some measurements, I think what happens is that in the figure below, we would consider the cursor to be at (XB-XA,YB-YA).  Apologies for the poor ASCII art.

Note that changing the screen resolution seems to reproduce similar issues as well, but I haven't managed to come up with a reliable STR with that.
Happend in Don Mills this morning, just connecting my retina mac to the monitor, and dragging the browser to the external window.  It did "fix" itself after a second drag to the monitor.
Hmm, my setup is single monitor only, mirrored to an AppleTV.  In that case, things didn't seem to fix themselves.
