    Description

      Black hole are displayed instead of QWebEngineView, if it is placed inside QMdiSubWindow and some of MDI sub windows have WA_NativeWindow attribute. Note that there are also a drawing issue with QLineEdit while QWebEngineView is running. At the end, there is a crash inside QtWebEngineCore at windows closing.

      Please, use sources only from attached project with QtCreator.
      Try to change TEST_NATIVE_WINDOW define for testing without WA_NativeWindow attribute.
