How do I fix jagged fonts for flatpak gnome apps in KDE Wayland?

I've been struggling to find a solution for the last 30m. I tried the following

I already have the kde and gtk portals installed (it comes by default). I am using OpenSuse Tumbleweed. Those apps are running under flatpak

EDIT: It was a bug in XDG Portals and it was fixed

See this: Fonts look terrible

The linked workaround solved this for me but only partially. If you look further in the thread this may be fixed soon anyway.
I struggled with jagged fonts in many places, like the web and some apps, and what I did was go into fonts and manually disable any fonts that didn't have anti-aliasing.
@Fredol I've found that many times, just disabling hinting unnastifies fonts.
I don't use KDE but I need to do this for Firefox/Librewolf, give it a try?

~/.var/app/io.gitlab.librewolf-community/config/fontconfig/fonts.conf false
Does it look better in X11?
