When I took a Screenshot with the camera icon in Replay Mode of my aircraft, the screenshot that Infinite Flight took was distorted in the top left hand corner of the photo and the aircraft was not aligned like how it was in Replay Mode.
This is a known issue. It is caused by the fact that the time keeps going even if you pause the replay only on the top left hand corner. So sometimes the top left corner appears darker, or lighter.
Here is a great topic by @AvioesEJogos explaining it.
