> multiple monitors You are talking about a very rare niche case where one monitor runs with VRR and the other doesn't. Everything else is handled just fine with X. > screen tearing. "No screen tearing" just means forced vsync which is easily possible on X11 with a configuration switch or by using a compositor. Actually forced vsync is one of the great disadvantages of Wayland because it always comes at the cost of higher latency. > Wayland rocks those two challenges. And it sucks in every other challenge. Most importantly standardization and development. The Wayland API ecosystem is ultra developer unfriendly and complicated and will pose serious harm to the FOSS landscape which thrives on hobbyist and niche applications. It's so bad it wouldn't be far fetched to call it sabotage. (E.g. look at the hello world: https://github.com/emersio

The standard “hello Wayland” project[1] is basically that, using an interface called wl_shm. You still need to do some IPC in order to arrange for the environment to so that for you, obviously, so a library called libwayland-client handles the necessary Unix socket handshake, plus some more of that to tell the system you’re done with the buffer and want to submit it. It would be possible to isolate the first part into a reusable executable that performs it then execs you leaving a well-known mmapable fd for the buffer, but the second you’d still need to do yourself. (Wayland isn’t willing to just use a pixel buffer you’re still writing to—indeed I don’t think discrete GPUs can do that as opposed to requiring an explicit transfer to video memory.)

> there's nothing at the protocol level that prevents the long tail Severe over engineering, unstable interfaces, massive boiler plate and huge development overhead is preventing the long tail "at the protocol level". As example: Compare the Wayland "Hello World" [1] with X11 "Hello World" [2]. If you want to add the ability to take screenshots it gets exponentially worse. (Also the Wayland version is not even capable to render strings.) 1.: https://github.com/emersion/hello-wayland/blob/master/main.c 2.: https://rosettacode.org/wiki/Window_creation/X11#C
