Usually the content will be copied with stored dimensions (here: 1440×1080 pixels), regardless of the display AR, because deskewing would alter the frame content (pixel values would depend on the scaling kernel). I would say it is not a bug, it is working as intended. Deskewing is a convenience for the human audience, but in case you want to analyse technical content, you will need a 1:1 copy of the content as it has been encoded/stored/decoded.
