I am experiencing an issue with font rendering issue in GTK based applications (for example; Firefox, GIMP).
I've read a bunch of Google answers about this, but haven't figured out yet what to do. It is clear that something is wrong with the GTK theme, but what?

Any ideas on how to resolve this issue?
