Twitch New Video Player
If you venture into the Highlights area of the site, you'll notice a staggering quality difference between some recent highlights and older ones.
Twitch changed their video player. As a consequence, the "auto-play" is always on, too... not very bright, if you ask me. So, uh, you may wish to mute your volume should you head that way... because a bunch of videos will start playing.
It's pretty startling. Trust me on that.
