Thank you for reporting this issue.
I can confirm that is an alignment issue related to the number of the pixels in the alignment area. I have logged it in our Public Issue Tracking System - PITS. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - PITS Issue
. Due to the nature of the issue I cannot propose a suitable workaround.
