The problem appeared a few days ago, appeared only in Chrome. My site uses multiples of 3 sizes which I use with "rem" by setting html{font-size: 3px}.

Thank you for the report! Does this affect any browsers that use modern WebKit? Chrome forked many years ago, so new bugs are their own now. Also, what is the expected and unexpected behavior on the attached test? The button looks normal in all browsers I tested with, including Chrome for Mac.
