Short description of error
denoising creates artifacts when I put directly node mapping\normal in diffuse

Exact steps for others to reproduce the error
this is the file

play render whit denoising actived -> render with error
play render without denoising -> render ok
play render whit denoising actived and node "hue saturation value" between mapping and diffuse -> render ok

Event Timeline

Quite sure the denoising artifacts are from negative values, same as using musgrave texture as diffuse color

I can't test with GPU but when rendering with CPU, I'm not getting as severe artifacts as shown here


If it is with the same settings.

Figured out the difference. I was using an old development build from 18.8. which gave different result with denoising. Removing negative values before rendering fixes denoising in all of them
Ubuntu 14.04 64bit, gnome 3 fallback, nvidia graphics. Rendered with cpu, 32x32 tile size.
