Text double scaling under Hyprland when org.gnome.desktop.interface text-scaling-factor is also set

[tuolin]

Hi!

I recently transitioned from i3 to Hyprland and have Hyprland monitor scale set to 1.66667 and also text-scaling-factor set to 1.66667 as it was left over from the x11 setup. Per changes in #4338 now it resulted text being scaling too large compared to other apps, such as kitty, which don't seem to pickup the text-scaling-factor under wayland.

I can set the text-scaling-factor to 1 but the gtk_scale is rounded to 2(I have a 32'' 4K monitor) and the resulted text is still bigger than other apps. it'll be nice if kitty's scaling logic is replicated somehow. Setting it to 1 also means occasional switching back to i3 needs a extra script execution to reset the scale and font size. Implementing the fractional gtk scale later would still require resetting the text-scaling-factor when switching from and to x11.

I think this is intentional (?) The text scaling property on GNOME as far as I can tell is only used to implement the Big Text accessibility feature (where all text is scaled up 1.25x) and not as a replacement of fractional scaling of the entire screen.

Yeah, text-scaling-factor is only used to implement large text. Don't set it to be the same as your system zoom. We haven't implemented fractional scaling yet, but that's a known issue.

Thanks for pointing that out. This seems to be the norm with desktop environments.

For anyone's intereseted: I ended up with something like this in my hyprland.conf

Exec-once = gsettings set org.gnome.desktop.interface text-scaling-factor 1
Exec-once = echo "Xft.dpi:160" | xrdb -merge
monitor = ,3840x2160@240.02,auto,1.66667
xwayland {
    force_zero_scaling = true
}

and this with in .xsession

gsettings set org.gnome.desktop.interface text-scaling-factor 1.66667

with no GDK/QT variables set.

as:

1. I don't run full desktop environments
2. there's certain process running in the background under x11 that keeps updating Xft.dpi according to the gnome scale value. So I can't just set the gnome value to 1 and set Xft.dpi in .Xresources. I haven't figure out what this process is. My laptop does not have this behavior so it definately can be disabled.

Ghostty seems to scale with the hyprland fractional scale somehow, despite fractional scaling not been implemented.
