    Description

      When creating a QWebEngineView widget dynamically (after the main application has been displayed), the main window seems to disappear and then reappear. Spying in Windows, the main window seems to have been recreated with a new HWND.

      Our application only creates QWebEngineViews when needed to avoid the web engine process start slowing down the application.

      A test application is attached for recreating the issue. Press the button, then observe the main window disappear and reappear with the QWebEngineView displayed.
