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?
