ADDITIONAL INFORMATION
Another closely related consequence of this is that if you have Night Light
mode active and you boot with Plasma 6.3 on Wayland during the “night color
time”, then you won’t be able to start the desktop at all! You can fix this by
disabling NightColor inside ~/.config/kwinrc:
```
[NightColor]
Active=false
```
and then you can log in again.
