Compiz thinks you are clicking in an edge window when you are not

Bug Description

Binary package hint: compiz

Seems that there is a race in X11 where we do not receive the EnterNotify event for our edge windows, so this needs to be addressed since it messes up the internal state of compiz such that mouse click actions are not recognized.

Test it with the following testcase. Set the edge to something, put a window in the middle of the screen, mouse over to the edge and attempt to alt-drag the window. It should work.
