I think the reason this is hard is because your eye only thinks it is seeing the change occur after you touch, but it's just seeing the change occur after the decision to touch which isn't the same thing at all. Maybe not all the time, but more often than you probably think.

Since you can't go back in-time, what I suggest to arrange for the event (if it occurs slightly after the redraw) to be applied using the old display model (instead of dropped). If the redraw occurs slightly after the event (and you're right) I'd prefer delaying the redraw instead of delaying the tap.
