P: CR/LrC/LrD: Sony files have a yellow/green tint

Not sure how to test this. I just opened the file in ACR and it doesn't have any of the edits applied...

@martyn_hand_ , I had the same issue with the color changing between develop and library modules, but I rebuilt all of my standard previews and that issue was resolved. I didn't resolve the color shift, though.

I also have Sony A7iii files...

As a test. Do you see the same color shift in Adobe Camera Raw as you are seeing in Lightroom Classic?

You don't even have to export - I'm getting this in the develop module! Everything loads in initially fine and then when the image 'pops' the colour changes.

Running on Sony A7iii files

I've updated from 10.2 to 10.3 and now my images are all gaining a Yellow/Green cast...as if the white balance slider has been moved. From what I could tell it only seemed to affect my Sony Files, not Fuji but I didn't overlay test for long as I had work to do. Downgraded back to 10.2 and everything was fine again...after generating new preview for the images 10.3 had changed. 

I'm running a M1 Macbook air with 16GB ram and the files are from a Sony a7iii

Exported from a raw?

Can you upload one? 

Also a screen capture of both Export dialogs would be useful. After export, viewed in what application? 

Responded via email. 

I can upload a screenshot as a JPG or PNG right now. I'm assuming you want the actual image itself to be exported as a DNG, because I don't know how I would make a DNG out of a screenshot. I uploaded the DNG to my Creative Cloud. What email should I share it with?

The next step is screenshot your Edit workspace with an image and the edit sliders visible along with the film strip along the bottom.

The image you screenshot should be exported as a dng and shared so that we can look at to see if we are seeing anything amiss.  Is that possible?

I downloaded the driver and restarted lightroom, but the issue is still persisting.

Yep, the thumbnails are displaying the photos with the correct edits.
