This is one of the biggest UI issues I have with Fedora post-install, the
fonts are very jarring versus the whole Ubuntu/Mac/Windows experience.
It's a non-ideal way to present Workstation to new users. I've actually
filed a bug about this:
What I don't understand is why Ubuntu has great fonts hinting by default
despite these patents being out there. Do they use a different package or
configuration of the existing patent-free Freetype?
