Jan,
   I get the same thing here in a regular window (ie my desktop)
anti-aliasing etc is working fine.  But only in vnc or Xnest do the qt
applications give this kind of error.  Same version of vnc in 9.0 works
fine.  So I don't suspect vnc.

If you do (and you are right, it is butt ugly) disable it you still get
this same error.  But again only in Xnest or vnc.
