Photo with both screens
SUMMARY
When attaching an external monitor with lower resolution (laptop internal:
2560x1440, external/HDMI: 1920x1080) and using "Unify outputs" on Wayland,
outputs don't get unified but the external monitor's contents are shown in a
kind-of window in the upper left corner of the internal monitor's screen.
Note this works fine with Xorg; I can only reproduce this with Wayland.
STEPS TO REPRODUCE
1. Run KDE in Wayland. Attach external monitor with FHD resolution.
2. Invoke kscreen, "Unify outputs".
OBSERVED RESULT
Internal monitor stays at original resolution, external monitor lights up.
External monitor's display contents are shown in a subarea of the internal
monitor. See attached screenshot(s).
EXPECTED RESULT
Both screens go to the same resolution and show the same content.
