YouTube Studdering?

So I don't normally use the YouTube app on my Roamios but I thought I would give it try (normally just use my Chromecast). Well, on both my Roamios I get pretty consistent studdering and freezing?

Is anyone else seeing this? One of my Roamios is wired and the other is wireless so I don't think it is a networking issue. I have no problems with YouTube on any of my other devices.
