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

Hi,
I just compared an old Qt1 app with a Qt3 app.
The Qt 1 app has a dialog with 28 widgets, the Qt 3 app approx. the same
number.
If the Qt1 app window becomes visible (if it was hidden behind another
window), it is *immediately* ready, I don't see the redrawing.
Now the same for the Qt3 (KDE3) dialog: at first the formerly hidden part is
drawn in the background color (immediately), and after a moment of "thinking"
the widgets are drawn, beginning at the bottom of the dialog up to the top of
the dialog. I.e. I can recognize which widgets are drawn first and which are
drawn last.
A K6/200 should be able to redraw windows immediately, so Qt3 is incredibly
slow :-(
One thing: the Qt 1 app isn't i18n'd, but once the widgets are created this
shouldn't matter.
So, is it the unicode, or the richtext everywhere, or ... ?
This makes Qt3/KDE 3 app feel really slow. I can't understand how people can
claim that KDE3 has become snappier than KDE 2. KDE 2 was ok on this box, KDE
3 feels worse :-(
Bye
Alex
