"no new behaviors" is not quite true, since presumably this makes VP9 playback better. It may not be possible to create a non-flaky test for "more smooth", but I think it would be better to say something like that.

No new behavior in the WebCore part. :-) Agree. By the way, I think the layout tests can catch the issue if the "media in GPU Process" feature is enabled.
