Brave stuttering on youtube fullscreen

Hello, Im using the latest brave version 1.18.77 and I got stutters on youtube fullscreen on any resolution. I didn’t have that problem before. I have no problem on other browsers - firefox, edge, chrome… I didn’t try to disable HA because I don’t see the point to turn it off cuz its working fine with other browsers.
Is this problem already reported somewhere? Do you know about this problem?

I run the latest windows 10 and AMD drivers on my RX 570 8GB.
