I think they're referring to the extra frame of latency when scrolling on Android. But then again, I've literally never heard anyone complain about that, I honestly don't think anyone notices, I believe the GitHub issue had to use a slow motion camera to even capture the issue.
Sorry, but do you really develop your software as a professional engineer based on "I heard X from few people"? With all the bias and filtering your brain does for this kind of "metric"?
Do you not? Engineering is a tool for solving human problems. If humans don't have a problem, then there's nothing to solve. Engineering is not the end in itself but the means to an end.
