Around 19 mins, when Joy is with David in his workshop, it cuts from a close up of her clutching onto a notepad to a wide shot where it has suddenly completely disappeared.

At about 56 minutes, in a lab scene, David is holding a soldering iron by the part that is normally very hot when the tool is in use.

At 37 min, when Joy is on the rooftop with David, there is a piece of ADR dialogue "do you miss it, being out there?" which is out of sync with the picture.
