      The project in question is fairly complex and I'm unbaled to compile simple browser on Windows 10 using visual studio 2022. Perhaps, the high level concept could be clear enough for someone to figure the issue. Basic OpenGL renderer/3D application with dock widgets where one of them is a simple web browser.

      The code below causes QWebEngine initialization to crash.

          QApplication::setAttribute(Qt::AA_UseDesktopOpenGL);
          QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL);
          QQuickWindow::setSceneGraphBackend("rhi");

      Is there any combination where OpenGL widgets works while having a hardware accelerated web browsing in 6.7? This was feasible in 6.5, it seems to be a regression in 6.7.
