The issue should be self-evident.

Tested on macOS Tahoe.

Did anyone try this on an M5 Max MacBook Pro with lossless compressed raws from an a7R V?

My comments- I cannot understand the square in a circle. Is that the position of the cursor?

My Lightroom seems to give meaningful answers with the cursor on the image.

Examples

Cursor on Black ( Cursor Not visible with Windows snipping tool)

Cursor on Blue.

Regards. My System: Windows-11, Lightroom-Classic 15.4.1, Photoshop 27.8, ACR 18.4, Lightroom 9.4, Lr-iOS 10.4.0, Bridge 16.0.3 .

It's the white balance tool. I have it selected as a visual aid so there's no doubt as to which color is select and has no bearing on the bug itself.

Yes, I now see your problem. Thanks (Forgot about the white balance tool)

I cannot reproduce the problem in my windows system. Hope you get an answer.

Hi @Generous_view0D45, Welcome to the Lightroom Community forum! We could use a few more details to figure out the issue. Can you send your system info, a screen recording of the issue, and a numbered list of the exact steps needed to replicate it? Does this happen with all of your images? You can find your system info by going to Help > System Info, copying and pasting it into a text file, and attaching it here. Thanks! ^CH

Hi, there seems to be some confusion here. I don't see how a screen recording or a list of exact steps would be beneficial here, however I will do my best to accommodate your request. Unfortunately, uploading my screen recording to the forums fails for some reason, so the list of steps will have to suffice:

Select an image.
Open the edit panel.
Move the mouse over the image.
Read the RGB values listed.

I'm using a 16" M5 Max MacBook with 128GB of RAM
