Description
Using QGraphicsView::render() and QPainter to render the graphicsview's viewport onto a QOpenGLPaintDevice fails if the scene consists of a large image. This happens even though the image is fitted in the view, and thus, the image rendered is not large. If this is a limitation of this method it should be documented.
Steps to reproduce:
- run the sample attached
- press "Render" button
EXPECTED: rendered images appear on the QOpenGLWidgets
ACTUAL: the large image does not appear. only the smaller image used for comparison appears.
