Is there anyone who knows how to solve this problem?

It is a problem that happens in all browsers.
Before changing the window size it moves cleanly.
Change the window size while moving, the position will be shifted.
And, it has choppy. Tremble up and down as you can not click.
Is there anyone who knows how to solve this problem?

And sorry, my English. I used translator.

I don't know if it affects performance or not, but I've destroyed/rebuilt scenes on resize in the past.

var controller = new ScrollMagic.Controller();

function yourScene() {
  return new ScrollMagic.Scene({
    offset: $('#header').offset().top
  }).setPin('#header')
    .addTo(controller);
}

var scene1 = yourScene();

$(window).on('resize', function() {
  scene1.destroy(true);
  scene1 = yourScene();
});
