while scrolling IE 11 doesn't update (on time) the position of an element inside the viewport

Hi,

It's essential to check the following jsFiddle demo http://jsfiddle.net/rbtbar/1dudpeox/ to see the issue.

If you scroll the viewport, the position of the fixed element is not immediately updated, which makes a bad impression to the users. It happens only in IE. Neither Chrome nor FF got this problem.

Regards,

Robert
