  function lessGreedyScroll() {
    if (!tick) {
      tick = !tick;
      requestAnimationFrame(scroll);
    }
  }

  function scroll() {
    window.dispatchEvent(new CE('scroll:smoother'));
    tick = !tick;
  }

  global.addEventListener('mousewheel', lessGreedyScroll, true);
  global.addEventListener('scroll', lessGreedyScroll, true);

}(window));

mousewheel hack

Please note that simply adding addEventListener('mousewheel',Object); as no-op on top of your page will somehow fix the problem at least in Chromium for Linux.
