MBP retina screen flicker black?

Hello, after doing so much research and feels like getting no answer I decided to post on this forum, I hope I will get any answer 🙂

so I own a new MBP retina 15", it just came last week and I just start really using it yesterday. When I was working with photoshop i notice sometimes random black flicker will just flashes out in a milisecond. It doesnt happen only once but numerous times, a restart doesn't fix it.

Sadly I can't provide any screenshot here because it just randomly happen & gone so fast.

Anyone knows why and how to fix it? I'm pretty sad to find this problem in a really newly bought product 😟
