First off, i think this bug may be the same as or very similar to this
bug: https://bugs.launchpad.net/bugs/71619
Unfortunately i do not know what package this belongs to.
Steps to reproduce:
- Create two user accounts
- Login to User1
- Login to User2
- In Gnome, via the top panel you should have a clickable menu that lists the
users logged in. Click it and select User1 in order to initiate a switch from
User 2 back to User 1.
Result:
- The screen goes blank for a split second
- The desktop of User1 flashes for a split second (NO GOOD!)
- Screen blacks out and login box comes up (OK)
Expected:
Do not flash the desktop of User1. Confidential information can be seen and
this is def not OK.
