I've switched to Debian and tried to recreate my Ubuntu setup. I hit a hard wall: The combination of (Debian Stable) x (GNOME) x (X11) will not give me fractional scaling, a must have. Swap (X11) for (Wayland) and I get it, but (GNOME) x (Wayland) x (Quartus IDE) is a no-go.
What about (Debian Testing/Trixie) x (GNOME) x (X11)? [EDIT: We looked into it… the patch isn't there either. https://101010.pl/@nabijaczleweli/113761518557209347 ]
