@gfxstrand With vulkan changes for kepler in mesa 25.2, should we be able to hit the ground running in mutter/wayland with NOUVEAU_USE_ZINK=1 set?

Or is this too soon?

I've got drivers from Mesa 25.2 running via https://launchpad.net/~ernstp/+archive/ubuntu/mesarc and without zink things are up and running on my GK107M, but with NOUVEAU_USE_ZINK=1 I get artifacting over the entire display.

(It IS exciting to see OpenGL 4.5 show up when I run `NOUVEAU_USE_ZINK=1 glxinfo -B` though...)

@satmandu We're not flipping on Zink by default just yet for those cards because we only just got Vulkan apps working on them and we haven't really tested Zink much at all. We certainly haven't tested it as the primary driver.

That said, everything should work in theory so if you can file a bug at https://gitlab.freedesktop.org/mesa/mesa/-/issues with detailed description of your hardware setup, your compositor, etc. and some screenshots (or photos of your screen), that would help.

@gfxstrand (And this is in NO way meant to be a complaint - just a "Here's how it looks on hardware people might not be testing widely on." Thanks so much for your work on this!)
