Thanks, good to know. (Would be nice if this was documented though.)

The problem is that the channel mixer has a clamping function which
limits the values that are allowed to pass through. This is not
appropriate behaviour for the scene-referred part of the pixel pipe, as
it can result in exactly the symptoms you report. The devs are aware of
this, and there are multiple PRs looking at how to solve this. I would
expect that in darktable 3.4 they should settle on one of the solutions
being proposed.

After playing around with the channel mixer on some pictures, I get an
odd effect sometimes. Just enabling the module with default settings
sometimes affects the picture, the histogram jumps to the left and I
lose detail in the highlights. Seems to happen when I also use filmic
RGB. Is this intended, or a bug?
