I think this regressed when we switched to always start the wayland compositor. In AcceleratedDrawingAreaProxy::waitForAndDispatchDidUpdateBackingStoreState() we check if the nested compositor is running, which is always true now (if EGL and the required extensions are available). We should check if we are in AC mode instead.
