Comment 11 for bug 1437485

I've had this problem for months, and only now realise that the problem doesn't occur in HQ mode. But, I've previously mentioned it also doesn't appear when the video is embedded in another website, rather than being viewed on the Youtube site, and it doesn't appear in the webapp. I don't think these other cases use HQ mode, as they don't seem to take as long to load as videos in HQ mode.

So, the problem only occurs when viewed in the browser AND when the video is viewed directly on the Youtube website AND the video is not in HQ mode.
