Here follows a summary after several hours of struggle. :-) After upgrading to qt-4.5 the problem happens between kde4 and qt4 applications where it looks like the fonts are shredded. To see an example of what I mean see my desktop http://www.fep.up.pt/docentes/jamatos/desktop1.png with this nice artifacts. :-) Funnily enough I don't get this problem with non-qt4 applications on kde and if I change to gnome all the applications work as expected (including qt4 based apps). I have moved away .kde and .kderc but the problem remains. I have tried the same with $HOME/.config/Trolltech... and no joy as well. After entering the first time the same problem with fonts would appear immediately. I tried to use my wife's account that was empty and the problems does not show there so I suspect that there is some configuration file somewhere that leads to garbled fonts. Since I was running out of time and without further ideas I have downgraded to qt-4.4.3 where all works as usual. Regards, -- Jos? Ab?lio
