Youtube, Discord, Visual Studio Code are flickering with black checkered squares/vertical lines. Partial solutions to this issue.

No I see it in black/dark area "checkered squares"

This issue had nothing to do with "Dark area's", it was a tertiary data race condition causing DirectComposition to output garbage because the original data had been deleted before the compositor had finished using them,

What you're seeing is a lack of information in the black area's, probably a result of either color crush by using Digital Vibrance or some flaw with the displays handling of DSC.

Chromium OpenGL does not use DirectComposition, it uses legacy blitting.

I restored to default I got several crash from chrome after using opengl

After several trials I found this occur in HDR mode only not SDR. Is there a possible fix for that ?

My Sony smart tv also has it, so this can't be windows only' issue
I play video with usb stick or bultin- youtube player. But this is definitely related to refresh rate.

Just wanted to point out something after I saw this.
That checker pattern looks somewhat like tile based rasterizing pattern NV uses since Maxwell 1.0 :

It should NOT be visible under any circumstances though, so I'm not sure why you can see it (or if it's actually that).
