MacBook Pro screen with tingling

Hi everyone and nice to meet you.

I'd like to discuss about a problem I'm experiencing sometimes whit my MacBook Pro 13", the last generation one.

When I open my Mac and the screen lightens up, sometimes, more often this days, it shows a gray screen with noises, is exactly like when you go in a tv channel and it shows that gray/colored pixels. That frame last less than one second, and after that the screen shows everything normally.

I don't know if it is a coincidence but this started to happen after the last update. Usually when i finish using my Mac I click on the apple logo on the top-left of the screen and than click Stop, could it be this procedure?
