Hi! Thanks for reporting.
It looks like a border-radius rendering bug in the browser. Do you have an idea how we can fix it?

Hi all , its not happening in Firefox, it seems only happening in chrome based browsers.

I used transform: translateZ(0px); on div.react-colorful__hue.react-colorful__last-control which makes the dot disappear completely
