The graphics are using the systems X11 to do the rendering. VNC generally 
doesn't seem to have all the needed extensions so it looks ugly as hell 
(happens with KDE for example too).
You can (and should) force Qt to use the graphicsystem=raster, either by 
commandline argument to your app or with some global configuration.

Or you use NX/X2Go instead of VNC:-)

Have fun,
