Hmm. One thing that struck me, and I'm not sure why it hasn't before, but is the UI limited to being within the 4:3 aspect ratio (i.e. more towards the centre of the display) as opposed to moving out to the edges for widescreens? I'm referring to what you can see in the 7/12 of the first page screenshots of the screenshot page at divinity2.com (and throughout the video).
