Recorded my display misbehaving today: https://www.youtube.com/watch?v=p6FficHt0VM&feature=youtu.be At least in my case, these lines only appear after a while (~30 min or more). If I shutdown the computer and turn it back on right after, lines will still be there. However, if I wait a couple minutes before turning it back on, they won’t be there. The angle of the display doesn’t matter at all. Leaving the macbook on for long periods of time does make the problem worse. In this case, lines get darker and sometimes appear at the bottom as well. Ventilation seems to be working just fine and I can hear the fans kicking in during intensive tasks. Today when the lines appeared I placed my macbook in front of an AC unit and the lines faded slowly, so the problem is most likely heat related.
