A Few Generic Advantages Of Wayland
I) “Every frame is perfect.” Wayland's main goal
is that no matter the system load, no matter what is going on, it will be flicker
free, tear free, and flash free. Every frame is presented in the correct and proper
order (dropping frames is fine, but you wont get frame 199, followed by 205, followed
by 200 because they all got sent at roughly the same time and the server picked
them at random). Wayland knows what order they came in, what order they need to
be displayed in, and knows WHEN they were displayed because EVERYTHING has a timestamp
associated with it.
II) Minimal!!! We've learned the hard way what happens when
you have something do a lot of things that also has to maintain backwards compatibility--
26yr old mistakes are still biting us in the ass TODAY with X. Let the clients
handle things, they can change-- they can break things all they want because its
THEM who has to deal with the fallout of that breakage. We're helping to future-proof
Wayland by reducing the surface-area for mistakes.
III) Hardware specific backends. I'm sure some people saw
that the Rasberry Pi got a Wayland specific backend, and how it allowed the hardware
to be taken advantage of more fully. It wont be necessary for all things, most
things WONT need a hardware-specific backend...but it sure its nice to have it
available. It means we have freedom, we have choice to make specific tweaks if
we need to. Or if we realize down the road that the main backend has some architectural
flaw in it, we can change it out with one that doesn't.
