This began happening to me after an update yesterday. Fonts unreadable in qt4 apps, gtk apps fine. As I am using Kubuntu 9.04a6 64bit I had to fiddle around with the unreadable settings manager to turn off subpixel rendering, but that fixed it. Unfortunately now my fonts look awful. Hopefully this is the correct place to post.
