Yeah, it probably has something to do with this. In X11 sessions, the display server does not typically handle scaling. Instead, the desktop environments provide scaling preferences to UI toolkits that then do the scaling themselves. In Wayland, the display server does handle scaling.

In both X11 and Wayland, you should usually see most applications following your scaling preferences nowadays. In Wayland sessions, you can ensure that applications always appear at the correct size, though at the cost of "legacy" applications appearing blurry. This behavior is configured in the Display Settings in KDE Plasma.

Also possibly useful: if you like the KDE Plasma session, it has a built-in magnifier; just hold Ctrl+Meta and use the scroll wheel.

Presumably this leads to a more unified scaling experience. This was one thing I was concerned about before, as it didn't seem that way. That's a solid improvement on its own.

This is useful yes, along with the rest of your comments. Thanks for your help.
