Short description of error
Blur node is causing black squares when using denoise.

Exact steps for others to reproduce the error


Most likely to occur when doing following steps:

  • Make a mesh, like a chain (addon)
  • Shade flat
  • Give it a pbr metal shader , no roughness
  • Load .hdr or .exr environment map
  • Switch on Denoise with default options
  • Add a blur node in the compositor.
  • Everything renders fine , and denoise renders fine, but when compositor starts to do it's work , black squares appear.

Notes: gone when you switch the option on: Gamma or Relative in the blur node
