Well, it's my understanding that Xorg still cannot do per-monitor fractional scaling these days, have they fixed it? That was the major selling point of Wayland for me, as an occasional linux desktop user.
Retina MacBook Pro was released in 2012, about 13 years ago. Personally, I don't think Xorg is in a position to sneer at its competitor for being "beta in quality" after "15 years into making."
XFCE solves this by using XRandR multipliers which can be applied per monitor, where the canvas is really big and is scaled however the target display needs it.
I always thought I'd run into this issue when I got a machine with a hidpi monitor. Well I have one now and use it with a normal monitor and yeah I fixed it with a single xrandr command. It's not clear to me what exactly everyone's problem has been.
Part of me really feels like 90% of people's complaints with X is really just complaints with gnome. Maybe we'll quit hearing them when gnome finally stops supporting it.
This is why I jumped to Wayland: laptop monitor and desktop monitor with different resolutions/scaling. Xorg choked, Wayland worked. That said, moving to Wayland broke a ton of other stuff in my otherwise peaceful workflow. I really do not like Wayland, but I need to be productive on my machine.
People have sworn up and down to me that the fractional scaling stuff is possible in X but I read probably 10 guides on how to do it and it never worked. Bummer.
