Is Wayland, Nouveau and Plasma really this unstable?

I recently tried switching to Wayland but found out the Nvidia 470.x driver is not supported by Wayland.
So I took Nouveau in use instead, but it really is not stable to use. Applications crashing, Wayland session crashing or entire computer freezing.
System is up to date.

Especially the combo Geeqie and GIMP is very much unusable. Normally browsing in Firefox and viewing Youtube and such is functional.

On these crashes I get this in dmesg:

What is wrong here? This can't be normal?

Yes, nouveau sucks, pretty much par for the course I'm afraid.

Tried the modesetting driver and removed xf86-video-nouveau but that worked just as bad.

Re: Is Wayland, Nouveau and Plasma really this unstable?

xf86-whatever is irrelevant for wayland, you can try https://aur.archlinux.org/packages/weston-eglstream or apparently gnome, but otherwise wayland is unusable w/ older nvidia GPUs

Re: Is Wayland, Nouveau and Plasma really this unstable?

What does weston-eglstream do? Would it enable running Wayland with an older (470.x) Nvidia driver?
Gnome is out of the question.

Re: Is Wayland, Nouveau and Plasma really this unstable?

As pointed out in your other thread: nvidia 470xx does support "wayland", it doesn't support GBM, which most wayland compositors use.
Weston is the reference wayand implementation, a somewhat minimal wayland compositor/WM - the package in the AUR was patched by nvidia to support eglstreams (nvidia's then preferred API)

Re: Is Wayland, Nouveau and Plasma really this unstable?

Gnome is out of the question.

I can't complain about the combination of X11 + KDE Plasma (without Compositor) for the reliable handling of my old NVidia graphics card. This combination does what Gnome Wayland doesn't.
