*** This bug is a security vulnerability ***
You have been subscribed to a public security bug by Seth Arnold (seth-arnold):
When waking up my laptop from sleep, e.g., by opening the lid, the
screen flickers, alternating between the login screen and the desktop as
it was just before going to sleep. That could reveal critical
information and poses a security risk.
I would expect the login screen to be visible at all times during wake
up from sleep.
The wrong behavior occurs on every wake up.
Apport does not work for me, currently, so I post the bug here. I would
be willing to give more information about the bug. In particular, I
could provide a video showing the behavior.
