*** This bug is a security vulnerability ***
Public security bug reported:
My laptop is configured to require my user password after waking up from
suspend (or of course, after locking).
Expected behavior:
I close my laptop screen, initiating a suspend. Later, I open the laptop and am
required to enter a password before I can interact with my session.
Actual behavior
I close my laptop screen, initiating a suspend. Later, I open the laptop and am
shown my session unlocked. There is a short pause of several seconds (the
duration differs) where whatever screen I was previously on is visible, and can
be interacted with.
If I was viewing a sensitive document, someone could take a picture of
my screen before the lock kicked in. Also, if someone had a quick
reaction time, or if the screen lock took an abnormally long amount of
time to kick in (it is usually 2-3 seconds), they could disable the
screen lock or perform some undesirable action with my user permissions.
