screenshot of display configuration system settings

SUMMARY

I have two monitors, both the same make/model which may be why detection is intermittent, and the positioning seems completely arbitrary.

In kscreen I have set DP-3 to be on the left and DP-2 to be on the right with DP-2 as my primary display (though this doesn't seem to be an option in Wayland).

Intermittently, when booting or when resuming from suspend the order is reversed: DP-3 is positioned on the right and DP-2 is positioned on the left. I have to then manually open kscreen and reposition them. 

It does not happen every time which makes me think it might be to do with which one turns on/is detected first. 

I created a new account in case it was old kscreen settings from my old X login and it happens even if I have never logged into X on this account.

It does not happen in Xorg, only Wayland.

STEPS TO REPRODUCE
1. Configure the screens to be positioned left/right
2. Suspend/resume or reboot


OBSERVED RESULT

The screens frequently (~50% of the time) get switched.

EXPECTED RESULT

The configuration should be maintained through reboots and suspend/resume cycles.

Still an issue with 5.18?

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Plasma 5.25 or 5.26?

If it is, please change the status to CONFIRMED when replying. If not, or if you can't because you no longer use this setup, you can change the status to RESOLVED WORKSFORME. Thanks a lot!
