Steam fractional scaling should work since their big UI update a few months ago. Try launching Steam with this environment variable: STEAM_FORCE_DESKTOPUI_SCALING=1.5

Awesome this fixes it!

For those using the Flatpak: sudo flatpak override com.valvesoftware.Steam --env=STEAM_FORCE_DESKTOPUI_SCALING=1.5
