OIDN atrifacts with denoising volumes

I’m getting this artifacts on volumes when using Intel Open Image Denoiser in Compositor:

The blue and white objects are volumes. Ground is not.

Does it happened to anyone else? Thanks in advance for any help.

What happens if you disconnect the Normal and/or Albedo inputs from the Denoise node? The Normal data off the volumes might be confusing it maybe possibly.

The artifacts are still there without Normal/Albedo.
I should mention, that white/blue objects utilise OSL shader.

OK, I think I’ve found a solution. After appending all assets to a fresh scene the problem seems to be gone:

I’ll have close eye on it.
