Dear Community,

when I scroll on my QGraphicsScene, the added QGraphicsItems disappear.
I don't know why this happens.
I have overwritten the boundingRect() method and made sure that the Item is only drawing inside its boundingRect.

Is it possible that overlapping of different boundingRects produce this issue?

Does anybody have an idea why this happens?

Have a look at the attached screenshots.

Thanks a lot in advance!

Best Regards
Mark
