Found this video bug when i was watching this video.
In theatre mode video doesn't stretches to full screen. (pardon me for my poor choice of words)
After inspecting the page i found deleting this line of code fixes this weird behaviour
<div id="panels-full-bleed-container" class="style-scope ytd-watch-flexy"></div>
Edit: this has something to do with live chat panels because this is only happening in live videos or the videos that were posted as live.
