I have exact same problem as Brian: as my workspace shortcuts are involving Super and not Ctrl+Alt, Ctrl+Alt are never released and the workspace switcher stays.
To reproduce this with the normal shortcuts, it's a bit more complex than what is in the bug description:
1. Go to top-left workspace
2. Press Ctrl+Alt+Right
3. Release Right
3. Press Tab
4. Release Tab
5. Release Ctrl
6. Press Tab
7. Release Alt+Tab
=> All along the workspace switcher stayed over, and is still there.
No key works, and the cursor is invisible until your press/release Ctrl+Alt.
I'd say the workspace switcher should disappear much more easily. At least disappear as soon as the key combo which was used to initiate is not anymore fully pressed.
