It may or may not be unrelated, but it is disturbing as it hints at an interaction happening with that particular element, even though you are scrolling a whole list and not concerned about an individual item… On other platforms there is a flash too, but only if you actually clearly press on the item to open it or select it. I would venture that it would feel more tactile to delay the flash ever so slightly, so it doesn’t appear when scrolling.
Obviously the scrolling also should not be delayed, as that makes it feel sluggish.
