Hi!
I have a small numerical software http://seis.bris.ac.uk/~rs1909/pdde/
that uses GraphicsView/GraphicsScene. This used to work with Qt 4.3, but does not work with v.4.4 anymore. When adding items to GraphicsScene the view does not update, only when I resize the window. I was trying to add update(sceneRect()); all over the place, but still not working. Especially the rubberband of selecting a region does not even appear when I move to mouse, while it has nicely worked with 4.3.

Does anybody know what change could have caused this behaviour? Unfortunately I cannot give a small testcase yet, that would take some time.
Bests,
Robert
