SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Start with a 4K monitor plugged into a laptop, with the 4K monitor screen area to the upper-left of the laptop screen area (desktop is extended).
2. Observe that screen locks after N minutes of inactivity, where N is specified in settings.
3. Unplug monitor and plug it back in.

OBSERVED RESULT
Screen does not lock after any duration of user inactivity. Screen only locks with Cmd-L, as far as I can tell.

EXPECTED RESULT
Screen locks after N minutes of inactivity, where N is specified in settings.

This was actually a bug in Haruna Media Player -- whenever it was running, the screen wouldn't lock. I don't know if the external monitor status has anything to do with this.
Comment 2 Nate Graham 2023-04-10 02:29:36 UTC 
Generally it's considered intentional for video players to inhibit screen locking while playing video. If they didn't, then you could have the screen lock on you while you were watching the video!

However if the app is inhibiting screen lock while simply running--rather than while playing a video--that would be an app bug.

Can you do some tests to determine this?
Comment 3 Aaron Miller 2023-04-10 03:15:31 UTC 
Hi Nate,

I was able to inhibit locking just by starting Haruna (no media playing or even paused).
