      Description

      Creating a QWindow with a QOpenGLContext when there is a QWebEngineView causes the the GUI to appear to go blank except for the custom OpenGL widget. My guess is that the glViewport is getting corrupted because you can see strange results as the application is interactively resized. I've attached a PySide2 program that reproduces the bug. This is not a problem with Linux, macOS, nor Windows 10 with AMD or NVIDIA graphics.
