When I resume from sleep, the contents of my desktop (including any open windows, emails, etc) are displayed onscreen briefly before the unlock screen is shown. This potentially allows an attacker to view the contents of a locked screen. To reproduce: 1) Suspend a machine, e.g. by closing the lid 2) Resume the machine Expected results: Upon resume, the first thing shown onscreen is the screensaver unlock screen. Actual results: Upon resume, the first thing shown onscreen is the set of open windows that were displayed before the machine was put to sleep. After a second or two, the unlock screen is drawn and you have to enter a password to unlock the machine. This is reproducible on my system.
