      The reason is that the QQuickWindow and render control share a QRhi instance. This instance is deleted by the render control destructor (the QQuickWidget explicitly deletes this before anything else) and warns that we are leaking resources. The resources are later attempted to be deleted and we crash because the QRHI pointer is null.

      (tested on Windows)
