P: Shadows slider in Parametric Curve has abrupt transitions when moving to the left

Hi everyone,

 

Just wondering if anyone can help me with this bug. 

1. Using lightroom classic, or Adobe Camera Raw in Photoshop CS6 or Photoshop CC 2021

2. Windows 10

3. Slide the "shadows" slider in parametric curve and observe shadows and histogram

4. Expected result - from left to right shadows get pushed uniformly into the blacks. Actual result - at certain points shadows abruptly reform, unnaturally losing detail, as seen here:

This makes it very difficult/sometimes impossible to adjust blacks properly. 

I've already tried every combination of "use GPU for..." in camera raw preferences and fully updated each app. 

 

Thanks for any help!

    I can duplicate the behavior on my Win 10 machine and it looks just like what I see in your video.  I will write a bug. Please leave the video up so the Camera Raw team can review.

     

    Thank you for your report!

    Do you still see this issue in the current release of Camera Raw (14.x)?
