Short description of error

  • Starting with this file:
    20221205_model_human_0001.blend

  • Masking some spot using Mask brush
    Screenshot 2022-12-15 at 13.33.48.png

  • Press 'A' to access pie menu, choose 'Increase Contrast'
    Screenshot 2022-12-15 at 13.33.58.png

  • Set Iterators to 11
    Screenshot 2022-12-15 at 13.34.05.png

  • Change from Increase Contrast to Decrease Contrast
    Screenshot 2022-12-15 at 13.34.12.png

  • The old mask is gone, and the whole body is MASKED
    Screenshot 2022-12-15 at 13.34.17.png

  • As I went up in the Iteration Count, starting from 1, I could see the whole body is slowly masked. I was expecting only the boundary lines of the masked area extending or shrinking, not expecting to see the whole body masked.

I wouldn't say that this is a bug. The feature seems to work as intended, as decreasing the contrast will iteratively mask everything evenly.

Tbh I don't find the "Decrease Contrast" useful either, but changing/improving it seems more like a feature request.
