Lightroom 12.1 color reading issue

Hello,

 

Anyone experienced this issue?

Upgrading to Ligtroom classic 12.1, RGB color readouts were completly off on masks. Visually you could see the expected changes in contrast, brightness, etc while mouse over readouts showed the same numbers as before. So completly off. Like you could see that black areas were getting toward complete black, but the readout was still at around 14% in all 3 channels.
 
I downgraded my Lightroom to previous 12.0.1. which works just fine.

I cannot replicate this behavior in Lightroom Classic 12.1  RGB values reported under the Histogram adjust for masking changes.  Perhaps you could give us a step-by-step example?

I can't replicate on my Mac either. With or without a mask, the RGB values are identical in the same location. After creating a mask, what edits are you applying?

Hello,

 

usually on masks I edit exposure, shadows, highlights. Sometimes whites, blacks.

I have a constant workflow of products, shoot under exact lighting conditions and some colors have to match exactly (+ - 2%).

In 12.0.1 all was working well, in 12.1 not anymore. So I went back to 12.0.1

My RGB values changed, as expected with masks/exposure.
