tl;dr: this is a css animation issue with paper-checkbox that only repros on certain resolution, certain window size, and certain zoom level. Not sure if worth fixing as P1. +dbeam@ to judge prioritization vs effort.

----
long story:

dpapad@ and I dug a bit deeper, and found that the problem is with the way paper-checkbox does animations. It's using @keyframe animation with transform: scale(), which doesn't seem to animate very smoothly, and is rounding size and positioning, causing some jiggles during and especially at the end of the animation.

We compared this with the checkbox in history page, which uses "transition" to achieve the same animation result but a lot smoother (doesn't jiggle). see: https://cs.chromium.org/chromium/src/chrome/browser/resources/md_history/history_item.html?q=history_item.html&dr&l=119

our options are:
1) attempt to convince polymer team to let us change the way they do animations.
2) roll our own checkbox as we did for history.

Friendly ping to get an update on this as per C#4.

Gentle ping!!
Could you please respond as per C#4 & update the thread accordingly.
