Use QRhiWidget for the Qt web content view on macOS and render the current IOSurface-backed shared image into the widget's Metal render target. This keeps normal presentation on the GPU instead of painting a QImage wrapper over the shared bitmap. Force Qt Widgets' RHI backing store to Metal before QApplication is created so QRhiWidget can obtain the top-level QRhi even when the native window is created before the web content widget enters the hierarchy. Other platforms keep the existing QWidget and QPainter path.
