History

This still happens.

#3 Updated by Johannes Hanika over 6 years ago

that input is quite noisy, especially in color.

because monochrome is a per-pixel operation, it will choke on this.

i'd recommend using the equalizer => chroma denoise preset, pushing mix to 2.0 (increase if necessary).
