Comment (by celloexpressions):

 I can confirm this - remember seeing it a bit during development but
 didn't realize the theme was at fault (not nearly as bad as in the
 screencast, but still an issue in IE11 desktop on Win 8.1). I have a
 feeling that this is closely related to the JS that does the sticky header
 when there's a header image - which doesn't work in IE (#25144, which is
 only partially "fixed"). It seems to disappear when there is a header
 image, but the lag is so slight in the first place that I can't be sure.

 For me, the lag is just ''slightly'' unresponsive scrolling; the re-
 rendering part is probably the browserstack layer but might show up on
 slower machines too. I think we need to test a slow machine to confirm
 that this is a big enough issue to look into.
