I am on NixOS 19.09, and I switched to Wayland instead of Xorg, and this enabled the experimental “fractional scaling” feature.
GTK apps scale nicely, but Chromium and Firefox retain a
1 and they rendering things bigger but fuzzy.
Any idea if this is supported yet, and I just don’t have the right configuration? Or maybe I need an update or patch?
As a “workaround”, font scaling works, and it also sets the
devicePixelRatio of the browser correctly and they render bigger but sharp instead of fuzzy. As a nice side-effect, GTK/Shell UIs (f.e. title bars, and other parts) still render at the smaller size, which I actually like; the size proportion between font and UI is not bad at all (unlike my experience in Gnome Classic / Gnome 2).
Seems to me like we need two features: UI scale, and font scale, then we can tweak both to our liking while having the appropriate
devicePixelRatio in browsers.
