Glitching Happening For Sticky Component - Mobile Browsers

[dschinkel]

I'm noticing an entire screen repaint in Safari on my iPhone once I hit my sticky and the repaint is happening once the offsetTop kicks in for my sticky. The entire page goes white for a split second. Um, this is kinda a problem!

Here's a screencast demonstrating the problem. When you view this on my IPhone using Safari, it not only does that short jump down, but that causes Safari to blank out the entire screen for a split second. My wife noticed it as well.

and another cast of it

This is my React.js code.

import {Component,Store} from 'reactivate';
var ReactDOM = require('react-dom'),
    Scroll  = require('react-scroll'),
    DirectLink = Scroll.DirectLink,
    Link = require('react-router').Link;

const TableOfContents = Component({
    store: Store('/companies'),
    contextTypes: {
        router: React.PropTypes.func.isRequired
    },
    componentDidMount() {
        const el = ReactDOM.findDOMNode(this);
        new Ink.UI.Sticky(el,{offsetTop: 50, topElement: "#ft-company-profile", bottomElement: "#footer"});
    },
    render(){
        return (
            <div>
                <p className="margin-8"><span className="blue medium"><Link to="/">HOME</Link></span></p>
        )
    }
})

export default TableOfContents;

Second, I noticed that when I try to look at the INK site from my iPhone in various browsers (Safari, Chrome, Firefox) I'm not seeing your demos work at all. Here's what I see happening in each browser on my iPhone:

FireFox - I don't even see the sticky rendering in the demo at all

Safari & Chrome - I see the sticky but you can't interact with the demo, meaning you can't scroll in that box at all:

So I assume that this should be working. Why isn't it?

Right now I don't know if it's a problem on my side (how I've coded markup + using INK) or if there are real problems to be concerned about with INK sticky components.
