Steps to Reproduce

Create a browser source with the following HTML:

<!DOCTYPE html>
<html>
    <body>
        <video autoplay>
            <source src="https://static-cdn.jtvnw.net/default-alert-asset/v1/video/Follow.webm" type="video/webm">
        </video>
    </body>
</html>

Anything else we should know?

It only happens with hardware acceleration enabled for browser sources.

It only affects video playback, CSS animations are smooth.
