host: windows 10
guest: lubuntu 20.04 (also with previous versions, also with ubuntu)
Problem: when guest is in full screen and no action is done for a while, the host lock screen timeout is triggered
Desired behavior: when guest is full screen, host lock screen timeout should not trigger.
As an example, Chrome with youtube in fullscreen on host does not cause lock screen to trigger after some minutes
I cannot change nor disable lock screen settings on host
guest lock screen / screen saver is not triggered
Does anybody know how to fix this behavior?
