I dont seem to have the problem with available resolutions mentioned above, but this absolutely won't work in dual screen mode. If you attempt it, it treats your main itor like its a dual and smashes both 'screens' into ...
It is a single cable display. I also tried disabling my other two displays, leaving only the primary 3440x1440 active. Issue was still present in that configuration. [xrandr-wayland.txt](https://github.com/ValveSoftware/...
Please also upload a console output of "xrandr --verbose" log running in wayland session with native resolution. Also, is your display a tiled display (requires two display port cables)?
@zakk4223 Thank you for the detailed report! That is extremely useful. Could you also get a log with +pid,+tid,+seh,+x11drv,+system,+x11settings,+fshack,+win added to the default logging options?
