Subject Masking Issues

[Kylie22024308np6e]

I have been having issues with my subject masking lately.  It will not detect the outline of the person or any of the individual features; such as the hair, eyes, etc.  When a subject is selected, it only shows a box around where the person is in the photo...not the person itself.  I have an older version of Lightroom Classic on my laptop & have not had the issue with the older version; leading me to assume it is a bug with the newest update. 

Additional Information: 

Version: 12.3 on Windows10

Most problems with AI masking are caused by older, buggy graphics drivers. Try updating your graphics driver by going directly to the manufacturer's web site:

If that doesn't help, please copy/paste here the entire contents of the LR menu command Help > System Info -- that will let us see exactly which versions of hardware and software LR thinks you're running.

I updated the graphics drivers and that seemed to work.  Thank you

I have been enjoying the new selection mask function for some time. I love it. But today it’s not working. When adding a Sky mask, it says no sky detected. When selecting the background mask, it selects the whole picture. When selecting people to mask, it creates a rectangle around the person. What’s going on? I am not aware if I did anything that could inadvertently affect the mask function. 

Demo: when select people, it ends up with a rectangle.

Here is my system info. I am using Windows 11. But it detected as Windows 10 Business version. I have been using this system for LrC for 5 months without a problem.

Please try if it helps to update the graphic card driver:

[John29992336dlj4]

Yes, that solved the problem. Thanks!

When I click on person 1 in mask it just puts a rectangle around subject. If I click select subject it just masks weird areas. Won't pick up skies in any photos. But it works on Lightroom mobile. What's going on?

You may have to update your GPU drivers.
