I haven't seen screen tearing anywhere in more than a decade, so that doesn't have much weight with me, but I can see how it could be an issue for video editing (if OBS is what Google suggests it is). Now I'm interested in why X and Wayland would be different - screen tearing seems like it would be at a lower level (mesa?) than the display server? I don't understand how any of a modern graphics stack actually works though.
