If there’s only 1px different within a 7px surrounding circle, it will not be marked as a visual change. This does not apply to anything other than isolated 1px diffs.
Our experience rendering millions of snapshots indicates that 1px diffs are almost always a result of unpredictable browser rendering. By ignoring 1px diffs we hope to better surface relevant diffs and reduce the amount of noise in your builds.
