Bug Description

Impact
======
Using Alt-Tab to leave a fullscreen game and then return breaks the game by offsetting the game down by the size of the GNOME Shell top bar and to the right by the size of the Ubuntu Dock.

Test Case
=========
1. Run a game full screen.

I installed Steam and used Team Fortress 2 because it's free (but a very large download)

2. Press Alt-Tab or click a dock icon to switch to another window in the same workspace and then press Alt-Tab or click the dock icon to switch back to the game.

The game should display and function normally.

Workaround
==========
Switch apps again using any method.
