Inside a windows VM client, with kvm, videos look fine inside Chrome. Such as for Netflix videos.
But from the host with buister, there is tearing. I tried firefox-esr, chromium, google-chrome.
What can I do?
I run a very old version of enlightenment as desktop environment. And I run debian buster with kernel 5.7 from backports. I thought I would then build myself enlightenment for wayland but it was too time consuming.
Version: 0.22.4-2. Latest in buster, but very old after I investigated EFL and enlightenment.
I have the same problem if I boot using xfce. I just tried in Chrome and I had tearing. Not all the time but clearly I saw it. In Youtube videos.
I want to try gnome to see if wayland removes the problem or if I have a graphics card issue with nouveau. But I wait to see what you say first because gnome requires 355 new packages. And kde-plasma-desktop requires 429 packages.
I don't have an AMD or Nvidia card. I have intel integrated.
