Answer 1

Three things can cause IE 11 flickering/choppy/delay for fixed position element while scrolling:

1. If you have an "overflow: auto;" on the parent container element, remove it.

2. Remove background-attachment:fixed; from the fixed position element.

3. Remove border-radius from the fixed position element (mobile IE only).
