The leaves behind Charlie change and then change back during his discussion with Norman out on the deck.
After Charlie leans the baseball bat against the wall, it disappears when the camera angle changes. When the angle changes back to a wide shot, the bat has re-appeared.
About two and a half minutes into the episode, there is a hair on the lens of one of the cameras, and during shots from that camera, it runs along Charlie's leg, making it a lot more noticeable.
