Description Iyán Méndez Veiga 2024-02-23 13:58:59 UTC 
SUMMARY

All OSD notifications (volume, screen brightness, etc.) are displaced from their usual position after I connected an external monitor (configured to extend to the left). I attach one screenshot to show the current position of the notifications. The wrong position continued even after disconnecting the external monitor.


STEPS TO REPRODUCE
1. Attach external monitor
2. Try to change brightness, volume, etc.
3. Disconnect external monitor
4. Try again to change brightness, volume, etc.

OBSERVED RESULT
OSD notifications are not centered and close to bottom as usual

EXPECTED RESULT
OSD notifications should, in my opinion, only be displayed in main display. If a laptop is connected to an external monitor or projector, OSD should only be visible in the laptop, unless the built-in screen is disabled or, of course, in unify output mode. Why? Imagine the setup of a laptop connected to a public projector. Changing the brightness only affects the built-in screen and it is distracting for the people watching the projector (slides, video, etc.).

In any case, after removing any external screen, the position of OSD notifications should be correct on the built-in screen.

Can't reproduce the misplacement part on plasma git build, wayland -- OSDs appear in the right position after multiple connect/disconnect attempts.
Comment 3 Nate Graham 2024-02-23 21:38:44 UTC 
Also cannot reproduce with current git master. I'm pretty sure this is a known issue that got fixed a week or two ago, but I'm having trouble finding the bug report for it. Can you test again with the final release in a few days?

Aha, found it: Bug 452648.

I don't think this is the same bug. That old bug was always in the wrong position, while this is only when connecting external monitors and also not 100% reproducible. But sure, I will try again with the release of Plasma 6. If I still manage to observe that, I will reopen :)

Cool, feel free to. Hopefully it goes away on its own 😅

I am also hitting this, the volume / brightness OSD sometimes appears at upper left corner, or just attached to the left side of the screen somewhere. Usually happens after waking up the laptop from sleep, and might have something to do with external monitor waking up slower than laptop. But I'm not sure how to reliably reproduce this.

My screen arrangement looks like this:

It didn't happen when I put the laptop to the right of external monitor.
