I don't know what others call this type of problem but I call them "data smears" because it's like you smearing strips of color down from one wet paint spot to another.
I thought I was the only one that referred to this as a smear or smudge (I've used both to describe this type of solution in the past 🙂 ). Now you have me wondering if I picked up the term from you!
