Safari full screen video flicker

Hi,

I've been using Google Chrome since I've got my MacBook. I wanted to try Safari instead but I found a really annoying issue.

When I want to watch a video in full screen mode (YouTube or Netflix), the screen starts to flicker. It didn't happen on Chrome, just Safari.

I was looking for a solution and found that I should go to System Preferences > Accessibility > Monitor and uncheck the "highlight pointer witch shaking". It helped. Once. After I closed my Mac (so the sleep mode turned on) and the opened again the flickering came back. So I checked the button back on and it again help. Until I closed my Mac.

So now everytime I want to watch a video I need to uncheck and check back the button.

This solution is not good and it's really annoying.

Any tips how to solve this?

I’m using MacBook Pro 13" 2020 so I have only Intel CPU.
