When using Chrome and zooming out to 75% with a resized board as well, the green previous/new move square overlays imprecisely cover their respective squares. The right/bottom edge let the underlying square color peek out, which is very distracting.
(I don't see this in Safari or Firefox, but last I checked Chrome was the #1 recommended browser.)
Thanks for reporting. This has been a thing for a while (https://github.com/ornicar/chessground/issues/51), but I guess it's more obvious with v2, in some cases.
You and I have a very different definition of "very distracting", but I did notice it too.
