Fractional scaling is a thing. It is also per-monitor. Just have to enable it via gsettings.

    gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"

The problem with it is that X11 doesn't handle the scaling well. Tend to get blurry fonts with X apps.

Now that most applications are supporting Wayland this is less of an issue than it used to be.

X11 handles font scaling just fine. It has since the 1990's.

It's not suprising if some level of indirection on top of it broke it in some environments though. Perhaps it has something to do with gnome 3? It works with gnome 2, kde, and all the minimalist window managers I've tried.

None of those try to "scale framebuffer" though, whatever that means. If it means what it sounds like, whoever implemented it is incompetent.

per display scaling? Mixed DPI works pretty well with wayland.
