I rember, that kate got much slower, when it had been compiled with QT3 
compared to QT2, in the time of the big switch. If I replaced the kate calls 
to the QT text drawing routines with noops in both kate versions, the 
repaints of the other widgets needed nearly the same time for both versions. 

Just turning AA off helped quite a lot,nevertheless I stopped using my PII 
350/256MB Ram/UltraScsi computer for QT 3 (X11) / KDE 3

Kind regards
