Why are there full viewport updates? #431
Description
I noticed here that you have
self.setViewportUpdateMode(QtWidgets.QGraphicsView.FullViewportUpdate)is it dangerous to set bounding rect viewport update instead?
self.setViewportUpdateMode(QtWidgets.QGraphicsView.BoundingRectViewportUpdate)When dragging nodes, I noticed the full updates cause like 70 (I think) unnecessary repaints on top of the expected path repaints. This was causing lagginess for me, especially when other animations are happening at the same time
