I'm literally reading your posts and responding to your words.

The real issue is that even today, some apps (Firefox, gedit, some terminals) don't adjust their scaling to the new screen

This shows you dont know what fractional scaling is otherwise you would have used the term.

I work in Linux as a daily driver for work and personal. I don't care what the tools are, but they need to work and stay out of the way. Right now, Wayland implementation of multi monitor for my hardware is too much bother, I'll try it again in a year.

This is you being stubborn because you're justifying your inaction based on false manufactured premises.

I have no objections to Wayland itself, but I value the kind of stability xfce gives me, which is stable, predictable, and gets out of the way. Right now, on my hardware, Wayland/gnome is not there.

This shows you don't understand what Wayland is because you compared a compositor protocol to a desktop environment.
