I'm curious if anyone is noticed the flickering Loading icon when the .mp4 version loops? It only shows up for 50 ms, but seems kind of annoying. Or maybe it's just my machine?
I saw it too. The odd thing is that 4chan's equivalent doesn't show any such loading indicator. Also, looping a video in HTML5 doesn't require Javascript.
