Looks like an antialiasing or upscaling issue.
Would there be any problem with reverting 251723@main?
Simon Fraser (smfr)
Looks like one is a non-Retina image. Possibly affected by an earlier test in the sequence.

I didn't try, but it seems unlikely that it can be reverted cleanly, because of 251965@main.
