chromium youtube , firefox youtube , etc , using any compositor , on gnome

desktop , or distro because the problem is present on gentoo which i have
everything compiled myself , happen on arch linux too , and today i discovered
that happen on opensuse tumbleweed 


with modesetting ddx glamor the problem is not present works fine . 

but i use intel ddx sna on my laptop for better performance and use in
conjunction with intel vaapi to play videos or play games.
