    Hello, I have a question related to Canvas in QML at Qt 5.1.

    When QSG_RENDER_LOOP=threaded, Canvas animation is normal.
    But when QSG_RENDER_LOOP=basic, same animation is slowy 2~3 times than normal case.
    So I set "renderStrategy:Canvas.Threaded" in QML, then speed is normal but scene is flickable and not clean with aliasing and it crashed after repeat tests .
    Do I need to set something?

    Thank you.
