The glitch seems not obvious in the attached GIF. I also tested the Nightly 57.0a1 and Chrome with your STR, both results looked identical. Could you double check again?
It seems that this issue is no longer reproducible with both latest builds and the previously affected ones. This may have been a website issue. Thanks Astley for the heads up.
