Yeah while Wayland still has some warts it seems like people say "I don't have proper color management on Wayland" with the same enthusiasm "This GNOME Wayland session crashes on boot" from a nearly a decade ago.
This Plasma Wayland session crashes (in my GPU driver):
- 3 years ago
- 1 year ago
- 6 months ago
The biggest issue I have with Wayland is that it requires a lot more out of a GPU than a framebuffer, and my experience with video drivers on Linux is that they are very buggy and not maintained for very long.
I have an older computer that I can run Xorg with compositing disabled and firefox with GPU rendering disabled. As far as I can tell I will never be able to run Wayland on it without changing the GPU.
Similar issues with some ARM based SBCs; they have varying levels of stability in their graphics acceleration capabilities, and often only on a very old kernel, but I can get a reliable framebuffer on mainline.
Wayland in itself has no special requirements on the GPU; it needs standard kernel support (KMS, dmabuf). EGL is optional, for both compositors and apps. Mutter and Sway can both happily run in QEMU framebuffer.
