[Bug 1545900] [NEW] When I go to unlock the screen after the system has auto-suspended, the contents of the desktop before suspend are briefly displayed

 

Public bug reported:

When I hit the power button to wake my laptop after it has automatically
suspended, the contents of the screen before suspend are briefly
displayed before the password screen appears.

This is a security issue as an unauthenticated user can see the last
thing I was looking at before the system suspended.
