Slightly offtopic but can you point me to a description of said font issues? My Android Studio (IDEA) fonts seem fine (on latest Kubuntu and Fedora w/ KDE).
I don't know what changed - if it was something in Fedora, Java or what - but I'm pretty happy with how things look now, whereas before I couldn't stand it. I tried all the java switches and what not to no avail - but now it just works.
All that said, KDevelop has made such great strides I can see it becoming my primary environment for all my development.
