I think it's here where you're failing. You don't have to ask for a
new pixmap in terms of the view's dimensions, but in terms of the
scene's dimensions instead.

It doesn't matter whether the view is 400x400 large, the only things
that matter, from the point of view of a top level QGraphicsItem, are
the scene's dimensions. So, to make things easier in the games I've
been working, I always make the scene's rectangle coincide with the
view's geometry.

Have you tried this approach?
