It depends a lot on your desktop enviornment/window manager, distro, hardware, etc. I personally find Wayland works perfectly out of the box whereas X11 still to this day has issues with basic stuff like screen tearing that needs me to add a line to my xorg config file to enable the driver feature that stops screen tearing. (Note that every other display server has zero issues -- MacOS, Windows, Wayland, etc so the fact X11 still suffers from this in 2024 is a strong indicator of its suitability for everyday use). For me the GNOME/Debian/Wayland on Intel GPU has worked flawlessly since Debian switched the default to Wayland a few years ago. The same combo has been problematic for X11 for years until Debian switched over to Wayland and it has been great ever since. Firefox has supported GPU/Video acceleration in Wayland for several years as well which has solved that particular bugbear. I understand though that other combos (particually the less-used DE/WMs and/or closed-source GPU drivers etc) are better for X11 for legacy reasons however I suspect with time these issue will be resolved.
Maybe you are not sensitive to it. Some people dont percieve tearing as much as others.
I run base PopOS (ubintu derivative with gnome) and i get tearing in x. I don’t know much about linux jist that when i login i can choose x/wayland and wayland seems to be a lot better at everything (fractional scaling also works).
I can consistently trigger it playing a video in any player under X11 e.g. videos in Firefox or in a standalone player like mpv/VLC etc. It's pretty damn obvious in certain types of videos e.g. action movies. But always on Intel GPU so it's possible it's not so noticeable with other GPU due to hardware or driver software differences. The Intel driver for xorg has a configuration flag that stops screen tearing.
IIRC I get it in Firefox occasionally. I vaguely suspect some combination of smooth scrolling, video, and a portrait mode screen but it isn’t annoying enough to investigate
