Disconnecting and reconnecting external monitor results in display corruption at screen edges

Disconnecting and reconnecting an external monitor in Unity results in the outermost pixel rows and columns at the screen edges to assume the color of any window that is dragged over them. Those colors then persist, resulting in permanent border artifacts. This issue is only resolved after restarting or logging out and logging in again.

Steps to reproduce:
1. Connect an external monitor to a laptop and set up the display configuration to disable the internal display when the external monitor is connected.
2. Now, with the external monitor enabled and the laptop display disabled, disconnect the external monitor by unplugging the display cable. The internal laptop display will activate.
3. Reconnect the external monitor and wait for the displays to revert to the external-monitor only configuration.
4. Open any window, drag it across the screen edge and away from the edge again. You should now observe that there is a set of pixels at the screen edge that retains the window color (white in the attached example pictures).

The correct behavior should be that the pixels at the edge should not retain a 'ghost image' of the window that was dragged over it.
