Recently I’ve upgraded from 25.05 to 25.11, and now my fonts looks terrible again. I use a font config on my home-manager to have more pretty fonts, but now it’s not working anymore.
after a while I figured it out. I checked for any font related config under my user and found this one, so I just renamed it to .old and now everything works again.
The previous thing about Gnome not loading the custom fonts weren’t true too. After checking it, it turns out that it takes a long time for the fonts to load, which gives the impression that it couldn’t find anything.
