Does it work for you in Gnome Wayland session? Do you use fractional scaling? Do you use any XWayland applications, like VSCode or Jetbrains products?

Oh, so your problem isn't with Gnome but X applications, having issues with fractional scaling and X itself not supporting different scaling amounts on different monitors?

Per screen fractional scaling has been available for years (even in Electron), if these particular applications don't support it, it's not because they can't but won't.

Although VSCode does claim to support it.

I don't because I bought an appropriate monitor. As I said, Gnome works great for me.

MacOS doesn't let me change the volume of my external speakers.

MacOS doesn't let me move windows between virtual desktops without having to switch to the touchpad.

MacOS doesn't let me easily snap a window to either the left or right side of the screen or even maximize it with the keyboard.

It's lacking so many really basic features.

Nope, my problem is with Gnome. Plasma has implemented proper fractional scaling for XWayland. I guess if Plasma works but Gnome doesn't - the problem isn't about the apps, it's about the compositor.
