Like screen recording. Popular Wayland native apps not dependant on Xorg. Wine working on Wayland.
Tangible benefits of switching to Wayland. And by those, I don't mean "no screen tearing", since it practically did not exist on most desktop environments with half-decent compositors.
Chrome is as wayland native as xorg native it is. It has backends for both. The same is true for Firefox.
And no one ever said that every program will have to move to Wayland, XWayland was created specifically for legacy applications to be usable that won’t port over. (Though their number is limited, since most applications use a framework like gtk/qt/electron whatever and all of those natively support wayland without changing the programs).
I run X11 as my daily driver in a 3 monitor setup and I regularly see tearing scrolling on a page in Kwin which I think qualifies as a half decent compositor, right?
You can use kwin with compositing disabled or by setting some obscure tripple buffering flag in its configuration.
As far as I understand it had sync issues even on single monitor setups until relatively recently because it did not try to sync at all and instead just refreshed everything based on an internal timer.
