Hi,

I still have this issue with Arch linux and Plasma 5.26.2 wayland.
After switching video output to secondary monitor (two monitors attached, only
one active) under wayland, KDE cannot find the primary output.

I use the 'Display Configuration' widget on my main panel to switch around the
video output, and after the first 'primary to secondary switch' ('Switch to
external screen') takes effect, the only option to switch output around that
works is to click gain on icon 'Switch to external screen'.

Note that this dos not happen if I extend (either left of right) using the
widget, KDE retains the primary output and clicking on 'switch to laptop
screen' works: only primary out is active and secondary is turned off

below error from journalctl -f when using ('Switch to external screen')

```
