@YouTube your new full screen feature is off. With respect it isn’t pleasing to the eye and makes the video look off center with this weird ugly boarder. I’m watching a video now and seeing that weird boarder bugs me.
Please send a feedback report directly from YouTube with these steps: https://goo.gl/WdI0BK . While every individual report may not get a direct response, we do review everything and use the details to investigate and fix issues. Thanks.
