Thank you for your post.
I am able to replicate the issue. The issue also occurs if you zoom to 150%.
"Enlarge Window contents to improve readability" does not exist under Mac OS X, and zooming to 150% does not affect the output under Mac OS X, so this is a Windows only issue.
I have sent your post along with my findings to our Development and Testing departments for review. When I receive any feedback, I will let you know.
