Flickery screen MACBOOK PRO 2020

As it turns, my MacBook Pro 2020 has been streaming videos poorly since I bought it. I took it to the support centre where I bought, and both times they told me it had no issues whatsoever, but the screen remains flickery when streaming any videos, particularly Netflix. On Chrome, Netflix streams in a very low quality.

PLEASE HELP!! I've already reset the PRAM and all those things.
