However, if you want to track it down further, you could try different kern= el versions between 5.10 and 5.15 to see at what point the trouble begins. But doing this requires that you get reliable testing results, which might not = be easy if the problem occurs only 20% of the time. --=20 You may reply to this email to add a comment.
