    Happens on my 1980x1200 as well. For anyone searching, here is a forum thread for this issue:

    I can still replicate this bug with 16:9, but it was more difficult to find a camera angle to trigger it. Try adjusting the Oscillate Transform component on the Main Camera to rotate between Min: 5 and Max: -20 around the X axis when running 16:9.
