visit the following page in IE10 and IE11, and use your mouse wheel to scroll the page:
http://www.oussamaharb.com/
In IE <= 10, Safari, Chrome, and FireFox, the header section of that page stays put when scrolling. However, only in IE11, when you scroll the page the the header jumps around and jitters. Essentially IE11 will do this on any div with a fixed background image.
Note the jitter does not happen if you grab the scrollbar with the cursor and move it up and down (which people rarely do). Some sort of bug when using mouse wheel has been introduced in IE11.
