Bug Description

[Impact]
The user cannot exit from screensaver if a menu or an applications grabs the screen. Fixing this bug will make the lockscreen experience more reliable.

[Test Case]
1) Call something like
sleep 3 && gdbus call --session --dest com.canonical.Unity --object-path \
/com/canonical/Unity/Session --method com.canonical.Unity.Session.ActivateScreenSaver
2) Open a menu within 3 seconds

The unity screen is turned off, but moving the mouse or hitting the keyboard won't hide the unity blank window.

The same issue happens if the lockscreen is configured to start after X seconds after the screen has been turned off.

[Regression potential]
Make sure screensaver works with and without grabbing.

Unable to reproduce the bug (in VirtualBox - low graphics mode, single monitor) so I can't verify the fix. Unable to switch to non-lowgfx because I get 'No such key 'lowgfx'' when trying to run `gsettings set com.canonical.Unity lowgfx false`.
