MacBook Pro 2017 Problem graphics

Hello

I bought a new MacBook about 2017, less than a month ago. And now I started to notice artifacts with graphics. Red stripes, distorted picture. Using the screenshot, I can not save this effect. Yesterday, after installing 10.12.6 there are no improvements. Is it a software issue or carry under warranty? I know that there was a problem with 16 years, with 17 to the most? Thank you.
