What version of macOS are you using? I can't get momentum working here any more and I don't have any option that I can see in the system preferences to turn it on or off. I can't think of any reason that momentum scrolling should flicker when normal scrolling doesn't, they use the exact same mechanism. Does it happen when you run emacs -Q? -- Alan Third
