P2715Q, vertical 1px line

This question is not answered

Purchased the monitor in May 2017 at Amazon.jp, use it with macbook pro.

S/N: CN-0GGK8D-WS200-745-8QFL, REV: A05

Sometimes a vertical line appears in the right side of the monitor, now it's purple/magenta color, but it also was red and green. It disappears after some time, but then comes back after a few days.

It is present with all cables disconnected and in self-test mode.
