Same thing on update of Jaunty (Kubuntu). Ok for several weeks until today. Not sure if today's apt-get upgrade did it or install of gtk-gnutella did it. Removal of gtk-gnutella and reboot did not help. Only on KDE apps. Non KDE apps are ok (firefox, tbird, oOO etc.) Was also adjusting the anti-alias settings in KDE today but put them back to default (system setting) before I noticed this (now KDE setting page has these bad "fonts" so can't check).
