I believe there are two different issues under discussion here. See screen shot below… I think @kofa (and myself) is referring to (A), thye very fine red line at the edge of the image, while @Terry I think you are referring to (B)?
I understood the OP’s question to be about (A), but there was a reference to (B) as well.
Apologies if I misunderstood.
