screen visible just before lock screen is activated
Ubuntu 20.04, gnome-shell 3.36.4, Xorg
When resuming my laptop from suspend (i.e. opening lid) the entire screen is visible just before the lock screen is activated.
Steps to reproduce
- enable lock screen etc.
- suspend by closing lid
- resume by opening lid
The screen with all the window content is visible for about 1 second. Then the lock screen is activated.
What did you expect to happen
The lock screen should be activated as soon as the laptop goes into standby, and do not expose the window content on resume.
