Launcher and global menu not redrawn after showing desktop

[Jarmo Kivekäs]

The launcher and the global menubar at the top of the screen are not redrawn nor accessible after choosing "Show Desktop" from the application switcher if the window active before switching is in fullscreen mode.

The bug can reliably be recreated by:

1. Opening 2 windows (does not matter what application, it seems) and enabling fullscreen mode in one of the windows by hitting f11.
2. Choose "Show Desktop" using the alt+tab switcher
3. Switch to the non-fullscreen window using alt+tab. The non-fullscreen window will become active and work fine, but the launcher and the menubar at the top are not present
