"This site appears to use a scroll-linked positioning effect. This may not work well with asynchronous panning"
<p>I have been given this unusual warning from Firefox. The positioning effect it refers to is a <code>div</code> I rotate as a factor of the scroll height. I have never had any problems with it, but is this something I should be concerned about? Is there anyway to have such effects without this warning?
The JavaScript that demonstrates this issue is:</p>
<pre><code>$('.gear').css({
   'transition': 'transform 1s ease-out',
   '-webkit-transform': 'rotate(' + Math.round(wScroll / 2) + 'deg)',
   '-moz-transform': 'rotate(' + Math.round(wScroll / 2) + 'deg)',
   '-ms-transform': 'rotate(' + Math.round(wScroll / 2) + 'deg)',
   'transform': 'rotate(' + Math.round(wScroll / 2) + 'deg)',
});
</code></pre>
<ul>
<li><code>wScroll</code> is the current scroll height</li>
</ul>
