YouTube app freezing when trying to play 60fps video?

So, the YouTube app finally supports 60fps video, and it defaults to it whenever I'm on Wi-Fi, however, whenever it tries to display any video at 60fps, it just freezes on the first frame it buffers and all I get is the audio playing over that frozen frame. I have to switch it to 480p/30 to start properly watching the video again.

Is anyone else having this issue? Is this can be fixed, how do I go about doing that?

I'm on stock 4.2.2 rooted.

Thanks!
