      Runtime warnings appear when QSGRendererInterface::MetalRhi (or QSGRendererInterface::Unknown which defaults to Metal) is selected.

      UI API called from background thread: -[NSView layer] must be used from main thread only

      I also observe some random crashes in the Metal thread, though in debugging mode only. This is probably related, but not sure.
