Did you use adaptive Sampling? Try to increase the "min. sampling" to avoid errors in the noise estimation in very noisy scenes.

Yes. And without adaptive sampling the issue does not appear, I just figured out.

It does not solve all, it makes it better.
So I made some tests:
- Minimum Samples: 512 Pixel Grouping: none
- Minimum Samples: 512 Pixel Grouping: 2 x 2
- Minimum Samples: 512 Pixel Grouping: 4 x 4
- Minimum Samples: 2048 Pixel Grouping: none
- Minimum Samples: 2048 Pixel Grouping: 2 x 2
- Minimum Samples: 2048 Pixel Grouping: 4 x 4
- No Adaptive Sampling
