I’ve heard the same thing about Wayland and NVidia’s drivers. To me, it seems like Wayland was designed to push all the hard work onto everybody else. That way Wayland never gets blamed for anything!
Not having a defacto compositor was a major blunder and resulted in an enormous delay to the project, reputational damage, and numerous challenges for app developers.
What I don’t get is why they pushed the compositor onto WM developers in the first place. Compositing seems like way too low level of a task for a window manager to be concerned with.
