Just let it die already.
I have been running Plasma 6 on wayland since release with no issues. I even recently switched SDDM to wayland mode because they still default to rootful X (WTF!). If anyone cares to do the same:
$ cat /etc/sddm.conf [General] DisplayServer=waylandToo bad fractional scaling is still not universally supported. In Firefox it’s buggy and disabled by default (and pretty much abandoned), and using default compat mode (when app is rendered at nearest greater integer factor and then downscaled by compositor) has some strange font rendering issues and potentially worse performance (on 4K monitor the resolution Firefox would be rendering itself would be humongous).
Thankfully in my case I can just increase font size and it works much better than with fractional scaling.
What’s wrong with fractional scaling in Firefox? It seems to work fine for me with kwin_wayland. Even if I have different scaling on each monitor, Firefox seems to respect it fine. Some really old software is a bit funky running through xwayland but nothing showstopping.
