I'm using Greensock animations for a web app I'm developing. On iOS, desktops the scroll animation plays really smooth, there's no problem. On Android browser things get complicated. On some devices it plays good(Nexus 5, Galaxy S4) on others it's choking(Nexus 7) I've tried setting the z property(TweenLite.set(element, {z:0.1}) , using x, y instead of top, left but nothing changed. I'm wondering if there's anything I can do to speed up GSAP on android browser. Any help is appreciated. https://dl.dropboxusercontent.com/u/4605534/examples/ztyga_gsap_test/index.html
