Font problems with KDE 3.1.4 (anti-aliasing)

Hello! Has anyone experienced strange font changes after installing KDE 3.1.4? Mostly it is that fonts that previously were anti-aliased are not any more, especially in Konqueror, but I also had problems with the message display in KMail which used a much too small font. I reverted back to KDE 3.1.3 because of this. I suspect it´s a change in the qt libs, so I think it was a bad idea to base KDE 3.1.4 on QT 3.2.1. Or is something wrong with my setup? Did anyone else have problems? Greetings Uwe
