When I'm in a conversation and the person I'm talking to has more than one line to say, there are times when the person's position changes slightly. It's as if there's a slightly different viewpoint for each line of dialog. Thing is that if the position is just slightly different, it looks like a glitch and is distracting. This happens if the focus is mainly on the person's face. If the shift is between face and body, it's not distracting because the entire image changes. But if there's a quick transition between one facial view and another, it is distracting. At least enough for me to notice.
