New rMBP 2016 screen has developed a weird purple area. Is anyone else experiencing this problem? It happens on both Windows and Mac. I don't have time to take it to get repaired at the moment but am curious whether I was extremely unlucky, there is a manufacturing defect or I've done something which has messed it up. The purple spot (which is actually a huge cluster of purple and then evenly spaced pixels - there is a weird pattern in the middle too) has only recently appeared.
