QWebEngineView->render() throws nullptr exception
-
Hello everyone, having a Qt 5.15.5 that was built for x86, Windows, QWebEngineView and QGraphicsScene (used for off-screen rendering)
Rendering a QWebEngineView by render() method, and everything works-as-designed.
But, in some undefined scenarios, it throws some nullpointer exception within QOpenGLFunctions::glReadPixels: a pixels is nullptr.
I think that's may be a some strange bug that should be fixed, passing some screenshots of exception points
Point first: calling QGraphicsScene render() method
And then the last point where exception happens
If you need some additional data needed to solve a problem, then I can push a full stack trace maybe. The only problem is that this bug occurs really randomly, but often enough. Once in 35-40 minutes maybe
