drawing in Qt3 seems to have become incredible slow :-(

I just verified on the TrollTech website - Qt 1 didn't have custom widget 
styles. My bet is that the addition of those in Qt 2.x made things much 
slower wrt redrawing.

This seems to contradict this. Looking over the changes between Qt 2 and Qt 3 
I see less differences that can affect drawing performance.

Do you have the problem only on an all-KDE desktop, or also when running a 
single Qt-only app under twm? (To exclude apps like kwin, klipper, memory 
overhead and kdelibs)
