Lightroom Classic 11.5 | Color shift from library to develop module when GPU acceleration is ON

Hi Everyone, 

I was expriencing the same colour shift issue with my 16" macbook pro M1 using Lightroom Classic 11.5 Develpoment Modual and Ventura Beta with accelartion on. I needed to go back to Montery. Does anyone know if this issue is now solved in Mac OSX Ventura public and LR 12 on the 16" MacBook Pro M1?

Thank you!

First, the preview architecture in Develop is unique to all other modules and the most accurate preview of the data. You should always view previews there and elsewhere at 1:1 or greater and when comparing, use the same zoom for each. 
It is normal to see slight differences at 1:1 but if really excessive, the first thing to try is to disable GPU in preferences; better? If not, you might have a corrupted display profile. Recalibrate the display or whatever you usually do to create a display profile. When given the option to build this profile, pick Version 2 (not V4) and Matrix not LUT. As to viewing Develop module and Library and outside of LR, it helps to soft proof in Develop using the same profile used in Library (Adobe RGB (1998)) OR the profile selected in Export for the edited image. 
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it. This is why disabling GPU is an option as more and more functionality moves to the GPU in newer versions of many Adobe products.

Are you running MacOS Ventura beta by any chance? This is a known issue with this beta software and a reason not to use a beta OS on a production machine.
