If you’re unlucky in the same way I was, it could actually be a GNOME/GTK issue. Some questionable (?) font rendering decisions were made that for me caused all text in GNOME to be blurry. I hated it so much I switched to KDE but soon realized GTK apps had the same issue.
Eventually I found a fix that worked and now I’m happy. So, next time you can try this. In the file:
~/.config/gtk-4.0/settings.ini
You can add:
[Settings]
gtk-hint-font-metrics=1
Here’s the Arch wiki page that explains it:

If your settings.ini is in a different spot see:
