So applications using e.g. Motif or some custom UI toolkit have completely wrong sizes then?

Damn. I tend to build against an older GTK3 version, because GTK deprecated so much good stuff, but that means my programs won't work correctly for that. I need to look whether it's easy to backport this.

I'm not sure about GTK3. But I know that KDE plasma has a setting for legacy X11 applications (I think all this fractional scaling stuff requires wayland). It can render them as-is or scale them up (bitmap scaling).
