When a stylesheet styling background-color is set on QGraphicsView that has a QOpenGLWidget viewport, it can cause drawing artifacts. This happens when the QGraphicsView is zoomed in or out and only if the background-color is styled for the QGraphicsView.
Steps to reproduce:
- Zoom in with CTRL + mouse wheel
- Zoom out with CTRL + mouse wheel
- Note artifacts
- Run with -s (style sheets off): No artifacts
