This is interesting.

If you simply showed these to me without any context, I would say that
the first two (left to right) are hinted for screen display and the
second two are unhinted for WYSIWYG printing.

KDE-3 and Qt-3 always did fonts as screen hinted which is why some
applications (e.g. KWord) had font printing issues.  Since Qt-4 can do
it either way, KDE-4 needs to decide which way that the fonts should be
rendered.  So, this would appear to be a bug -- the GUI should always be
screen hinted.
