My current repro requires XITS Math (https://github.com/khaledhosny/xits-math/blob/master/xits-mathbold.otf), and Segoe UI Emoji. Do you have a machine with that font? If so, could you try the following? > > emacs-24.5 -Q -mm -l 21028.el 21028 -f prettify-symbols-mode > > I've attached 21028.el and 21028. When I run this command, each full redisplay takes about 5 seconds; same for pointer motion. Thanks. I think the evidence and the profiling data you presented quite clearly indicate where the problem is. So I think the efforts should now be directed towards reproducing bug#17125 and then solving it in some other way that doesn't suffer from performance problems.
