*** This bug is a security vulnerability ***
You have been subscribed to a public security bug:
I am using a remote application to AnyDesk to remote access my Ubuntu
16.04 LTS 64 bit. On the application we can resize the screen and have
the resolution of the target computer scale up and down when this is
done.
When the computer is locked on the login screen if the screen is resized
( resolution changes ) - For a brief fraction of a second the unlocked
screen flashes and the login screen shows up again. I think this is a
security breach to be able to peek into the inside contents even though
the computer is locked.
Please feel free to close this issue if this is an already known issue
or if its already fixed in later releases.
** Affects: lightdm (Ubuntu)
Importance: Undecided
