Windows 10 with Intel HD graphics and recent graphics driver from https://downloadcenter.intel.com/. On my system with Intel HD 530 graphics the driver is version 26.20.100.7262. We have users with other Intel HD versions and drivers > xxx.xxx.xxx.6709 with the same issue. But it may affect more systems, still getting bug reports from our users.Windows 10 with Intel HD graphics and recent graphics driver from https://downloadcenter.intel.com/ .

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.
