Mobile Safari bug on fixed positioned button after scrollTop programmatically changed…?

Question

I\'m just about done a webpage but there is one bug in Mobile Safari (iPhone and iPad iOS 5.0.1) with two buttons that are fixed to the upper and lower right corners..

Answer 1

After spending a couple of hours on this, I found a workaround: try scrolling (maybe with an animation) and then scrolling again to the same point (without animation).
This way you force the browser to delete the wrong rendering from the view.

Example:

$('body, html')
    .animate({scrollTop: 0})
    .scrollTop(0);
