removing itemChange did actually fix the bug I mentioned. So now I can wrap my items in item groups. This doesn't help with my first problem, though: Each time the position of the item group is changed, boundingRect() is called on all its children due to a call of fullUpdateHelper. That's exactly what I was trying to elide. I'm not sure were to go from here. Earlier on you suggested using built-in graphic items, only. This isn't really an option for me, as it would mean adding another layer of indirection (objects which manage state of graphics items + actual graphics items) and would make the code hardly more readable. If I had some time I would try to implement some caching mechanism in Qt itself, but I guess that has to wait for a while. If you still have any other idea, please let me know.
