Normally in GNOME when you hit the super key the windows explode so you can select between them, and the windows appear on the monitor that they're opened on.
I have 4 monitors, and since upgrading to 14.04 the Windows on my far right monitor always appear on my centre screen when I hit the super key.

Is this a known issue, or something to do with my configuration?
