Public bug reported:
When unlocking the screen, any window that is restored from a minimized
state is not drawn (it is just black).
[Steps to reproduce]
1. Open a window
2. Minimize the window
3. Lock the screen
4. Unlock the screen
5. Restore the window
[What should happen]
* The window content should be drawn as expected.
[What happens]
* The window is not drawn. See attachment
[Workaround]
* Any window action will paint the window again, for example re-sizing,
minimizing and restoring again, but not moving the window.
* Opening the unity dash or HUD also works.
