Is Canvas3D.fps equal to the entire windows's FPS?

  • Confusingly the Window type in Qt Quick doesn't have a fps (frames per second) property, but Canvas3D does. So I'm measuring my app's fps by having a dummy Canvas3D and displaying its fps property. Is this a valid approach? I think so, because the Canvas3D is probably redrawn exactly at the same moments as the window.

    I'd like your answers to provide either proof or a reference for what they claim, so I can be sure I'm getting the right performance measurements.
