Maybe a color depth issue here as well.\r\n\r\nA misidentified or misset depth makes sense to me -- as a color-depth layperson -- because of the way that the backdrop artwork \"corrects\" once the emulated video is displayed over the backdrop. That is portrayed in my immediately prior screenshot.\r\n\r\nI don't have any coding background in image or video so I don't know if I'll be able to take this issue much farther now, I'm afraid."}}
