So I downloaded an awesome (IMO) wallpaper and all that. Went to crop it to fit, and it shows these strange green marks on the side of it. The marks don't show up on the main wallpaper, but they do on the lockscreen. The picture itself is totally clear of them. Not using any roms and not rooted or anything. I am using Nova Launcher if that makes any difference. Any ideas folks? Thanks for the help.
