pianoroll view in musescore.org has annoying bubbles

I LOVE the new pianoroll view for musescore's website, but I believe the bubles getting out of the notes being consumed are annoying and disturbing. Maybe they just take too much place, but I feel like it's not worth the (cpu) cost.

Also, when you press pause, it just does not stop creating bubbles and burning which is also quite annoying.
