Description
QGraphicsScene::removeItem seems slow when there are many installed scene event filters in the scene (as a whole).
I.e. it seem O(n*m) where n is the number of items (children of item) to remove an m is the number of all scene event filters that are installed in the scene.
The culprit is probably this loop.
