You have a module w…ith a mask, and higher up the pipe another module is using it as a raster mask. So far ok. You now invert the raster mask in the higher-up module and notice that switching that module on and off causes the whole image to change, not just the part covered by the inverted mask.
This can be seen using the raw in the pixls.us item below and the attached XMP file (uploaded as .txt). Invert the mask in color correction to see the problem.
Please ignore the rest of the explanation in this post as it is wrong!
----------------------------------------------------
You have a module with a mask set up and all seems fine. Then at a later stage in editing, the module is affecting the whole image. You click on the mask button and the yellow mask looks fine. But it still is being ignored. (This is not the scenario where re-using a raster mask and you've turned the "source module" off)
This is very confusing and quite time-wasting.
Bill Martz discovered that a workaround is to duplicate the module here - https://discuss.pixls.us/t/deliberately-difficult-gamut-colors-in-macro-shot-of-hex-nut/20357/110
However I've been trying this and whilst it works initially, the duplicate can subsequently suffer the same problem.
In another image, I fixed one instance of the problem and then it happened in a different module later on.
This all leads to frustration.
The issue can be reproduced by taking the raw file in the above pixls post and loading this xmp which has been renamed to .txt -
[DSC08363-Nut-S-sRGB-freshDownload.txt](https://github.com/darktable-org/darktable/files/5719242/DSC08363-Nut-S-sRGB-freshDownload.txt)
Note that colour balance 1 mask excludes the nut but it is still altered by the module.
