MacBook Pro (2015) from sleep mode shows "rainbows, graphics card?

Question

macOS

I found a strange thing, it doesn’t bother me yet, but I know that it’s definitely not just like that, when you exit sleep mode, on a “cold” one, that is, for more than 10 minutes, it shows this picture. I would be very grateful for the opinion of the pros, what is it and whether to run for repairs. https://youtu.be/cysDscxE9Rg
