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

[Lee Revell]

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.

Looks like you are using a lightdm/Unity session. Re-assigning there

I did not check the security option when filing this bug, but I think it qualifies as a security issue.
