My setup: OS is Endeavour OS and up to date, my GPU is RX 560 with 1xDVI + 1x HDMI + 1X DP output, two monitors of the same model (1xHDMI + 1xDP). (KDE Plasma 5.27.7, KDE Frameworks 5.108., Qt 5.15.10, Kernel 6.4.11-x64v2-xanmod1-1, Wayland)

Original setup: MonitorA on left of my Desk connected with DP, MonitorB on right of my Desk connected with HDMI, the problem is that games see left monitor as "Monitor 1" and opens on left monitor all the time, and I prefer them to use "Monitor 2" by default.

Setup 2: I switch DP and HDMI cable, but everytime a boot up my computer (I set auto login in SDDM) the monitor configuration becomes "MonitorB is on top of Monitor A", none of my attempts to change that persisted between reboots, I didn't test games because this heavily affects my workflow.

Setup 3: Also switched monitors positions physically (MonitorB on left of my Desk connected with HDMI, MonitorA on right of my Desk connected with DP), now the default monitor configurations is side-by-side again, but every boot I have to switch monitors' position in settings or I have to go right on MonitorA to get to monitorB.

I also noticed monitor settings go away when I logout of Wayland KDE session, is there a way to fix monitor configuration in SDDM?
