[Interest] Slow refresh rate on QPropertyAnimation => pos for child widget?

Hello! I am getting pretty good refresh rates on QPropertyAnimation for QGraphicsScene, as the interval set in the qt source is for 60fps. But animating a child widget’s position looks more like 20fps. The widget in question is a child of the QGraphicsView.

See the following screencast, which itself uses a high enough fps to accurately capture the refresh rate of the widget animation.

Thoughts? Thanks!
