I forgot to add that my desktop environment is KDE, and so I'm using "xdg-desktop-portal-kde" (version 5.19.2).

Do you see any difference when you remove GTK_USE_PORTAL=1 ?

Yes, I should have make that clearer. When not using that environment variable (but still using the Wayland back-end), fonts render properly, and are readable.

I think you see https://github.com/flatpak/flatpak/issues/2861 which leads to https://gitlab.gnome.org/GNOME/gsettings-desktop-schemas/-/issues/31 whi

Should this maybe also block Bug #1609115, because this specifically affects non-gnome DEs?
