I can’t see this having been mentioned anywhere. I use Arch linux (BTW ), and have asked on the forums there, but nada. However, I’m thinking a Blender problem.
Nvidia drivers 555 (doesn’t matter the sub variant) are failing with CUDA errors. This on Blender 4.2.
Illegal address in CUDA queue copy_from_device (integrator_init_from_bake integrator_shade_surface integrator_sorted_paths_array)
Reverting to 550 drivers and all is good.
Except it gets weirder. Blender 4.1 seg faults.

Even with 550 drivers.
I can’t share a scene - uses Botaniq, so has paid for assets.
Tried re-installing CUDA and no change.
For now, I’ve pinned nvidia, nvidia-utils (and not that it matters, lib32-nvidia-utils) at 550, but any ideas?
The reason I’m thinking a Blender fault, is that everything else tested works just fine. Cyberpunk 2077, the three most recent unigine benchmarks (heaven, valley and superposition).
