Yes! I saw it at the 36 minute mark on the video. That had me curious. I think it was a trick of perspective, it first looked like some huge chunk of debris that the first stage flew past, but after watching it again, it looks like a little chunk of ice that got blown off of by the cold gas thrusters.
