Info:
Photoshop 25.12.0
OSX Sonoma 14.7
16 bit RGB files, tried multiple profiles
Working on external monitor
Issue:
Creating masks from selections, and Image Adjustments (Curves, layers) etc do not match previews anymore.
Here's video recording with voiceover
Steps to reproduce:
1) Make a color range selection
2) Make a mask
3) The mask does not match the preview in the color range selection, it includes a lot more darker tones
and
1) Select a mask
2) Image>Adjustments, make any adjustment to the mask to darken/lighten/change contrast
3) The mask does not match the adjustment preview, it includes a lot more darker tones
Expected (and how it always worked) result: The mask would match the selection
Current result: The mask is significantly different than the preview/selection
