A simple fix I've settled for is using this app: https://itunes.apple.com/ca/app/gamma-control/id974998622?mt=12&l=en
It allows you to modify the gamma values so that the screen never displays a total black or white, hence preventing the green or pink lines. Only catch is you can't use it alongside Flux or similar. I've changed the Black values by 0.04 and the difference colour reproduction is barely noticeable, but the lines are gone.
