Granted, I've always had these kinds of issues with new laptops, especially when it came to proprietary nvidia or AMD graphics (before AMDGPU) and I agree it's improved a lot, but I still need to tell people that there's caveats with some (especially newer) laptops.
In 2022.
That is the kind of basic thing that does not work.
In addition to that, if you have a high-DPI laptop display and you want to plug it into a low-DPI desktop monitor (or vice-versa), good luck getting the scaling to work in a usable way.
Sure? This is exactly the thing that Wayland was supposed to solve. Only X has one DPI for all screens.
I still use X because I'm on FreeBSD and I even got multi-screen multi-dpi scaling to work there, with xrandr settings but indeed it was not fun. In Wayland it should be click & play though.
It's not a fault of Wayland but it is reflective of the whole Linux laptop experience.
KDE's upcoming release in October should hopefully be addressing this by allowing you to disable the bitmap-based scaling.
