I am using the QGraphicsView widget on PyQt5 and I created some custom QGraphicsItems.

When I instantiate without any effect my items, I get this :

When I add those three lines :

        blur = _QtWidgets.QGraphicsBlurEffect()
        blur.setBlurRadius(1.1)
        self.setGraphicsEffect(blur)

in the “grand-parent” of my custom items, I get this :

Moreover, nothing seems to move, my mouse don’t move, the deck don’t do anything…

I found this post but it didn’t help me, every hint I passed as an argument made the same result.

I also tried to directly pass the blur effect on the QGraphicsView, but it only works when the QGraphicsView changes (resize, …) and is not applied with any update of the items.

What should I do?

Thanks for you help!
