Public bug reported:
If the first user locks his session and the second user tries to open
his own session, the second user can see images (thumbnails) in the
screen of the opened windows (applications) of the first user for some
seconds. This can break confidentiality.
This problem is sometimes reproduced even after restarting the computer
when the system is trying to start lightdm.
