This should be fixed for Unity. It is new behavior, and from the 41 people saying this bug affects them, plus the duplicate bug reports etc., it is a hassle for a lot of people. I even get the orange overhang on the screen when I go idle and my screen locks - the orange overhang is even on my lock screen.
I tried Raphael's suggestion. From a shell I ran "gconf-editor". Went to both 1/plugins/ expo/screen0/ options/ dnd_button
apps/compiz-
and
apps/compizconf ig-1/profiles/ plugins/ expo/screen0/ options/ dnd_button
and changed from "Button1" to "Disabled".
Have not had a problem since.
