How many sites put invisible DOM elements over the videos?
Remember, if you put visible DOM elements on top of the videos, then you lose scanout compositing no matter what.

A lot of them? Vimeo, for instance, has a number of opacity: 0 and hidden divs over the video. Twitch has at least a couple of opacity: 0 divs on top.
Maybe we're interpreting the phrase
> hidden empty div over YouTube videos
differently? That's the structure I assume they were talking about.
Considering that it's now optimized and that's not what the original post said, I don't know why you'd assume that.
That's what this "empty div" is for if that's the one I think it is. It is the container for things like branding and annotations.
