Impact
======
Using Alt-Tab to leave a fullscreen game and then return breaks the game by offsetting the display by the size of the GNOME Shell top bar (and the Ubuntu Dock if running).
Test Case
=========
1. Log into the default Ubuntu session. (Make sure that Wayland is running by running this command. If you have output, you are running Wayland.
env | grep -i wayland
2. Run a game full screen.
I installed Steam and used Team Fortress 2 because it's free (but a very large download)
3. Press Alt-Tab to switch to another window and then press Alt-Tab to switch back to the game.
The game should display and function normally.
Other Info
==========
This bug is split from LP: #1725649 where the problem was seen and fixed for the Xorg session. This bug is for the Wayland sessions.
