Steps to reproduce

  1. Get a display capable of something other than 60Hz
    (e.g. 75Hz, 85Hz, 100Hz, 120Hz, 144Hz, GSYNC, FreeSync, several models of DLP projector, Oculus/HTC Vive virtual reality goggles (90Hz), or other display).
  2. Open http://www.testufo.com or http://www.testufo.com/photo
  3. Observe EDGE is very stuttery and jumpy, while FireFox, Chrome, Opera, Safari, are all perfectly smooth at the same refresh rate.
  4. EDGE is hard-coded to 60Hz, in violation of W3C Animation Timing spec (end of section 5) … https://www.w3.org/TR/animation-timing/
    IE10/IE11 sychronizes smoothly at more refresh rates.
