Which distro./desktop environment are you using? I'm running a dual screen setup (laptop + 4k screen over DP) with fractional scaling on the laptop screen (150%). This works pretty well in Fedora 31, no blurred text. AFAIK different scaling parameters on different screens are not supported by Xorg, so I'm pretty happy with Wayland.

Kde Plasma Wayland with fractional scaling set to 125%. My workhorse applications are Libreoffice, Firefox and Thunderbird.

Each and every of these applications is blurry as hell. My eyes hurt. True that the multi-monitor experience with mixed scaling factors per display under Wayland is better, that's why I am still suffering of that stockholm syndrom.

Gnome does better, I acknowledge that, but their opinionated UI decisions make me feel like a retard.

That's because those applications use XWayland, which means Wayland scaling has no effect and it scales the pixmaps instead. Try export GDK_BACKEND=wayland.
