Created attachment 168513 [details] kwinoutputconfig.json before reboot SUMMARY When I start a new session with Wayland, I change scaling of my displays to 200% each and rearrange them. After that I set middle monitor refresh rate to 144Hz from 60Hz. Everything works fine, but then after I reboot my computer, Wayland session fails to start. All three screens are blinking, can't get into another tty. I use another account to get into X11 session and delete kwinoutputconfig.json file from affected account configuration files. After reboot, new kwinoutputconfig.json is created and everything works, until I do the changes that I mentioned. STEPS TO REPRODUCE 1. Start Wayland session 2. Set display scaling to 200%, refresh rate to 144Hz 3. Reboot 4. Wayland session no longer starts OBSERVED RESULT Failure to start session EXPECTED RESULT Configurations are properly applied and session should start SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux 6.8.4-arch1-1 (64-bit) KDE Plasma Version: 6.0.3 (issue is since Beta 2) KDE Frameworks Version: 6.0.0 Qt Version: 6.7.0 ADDITIONAL INFORMATION I have this issue since Plasma 6 Beta 2 and only on Wayland session

I found out that if I do not change refresh rate from 60Hz to 144Hz, everything is fine and Wayland session loads properly. Only when I set my main display to 144Hz, the issue appears and Wayland session is no longer starting.
