P: (GPU) Develop/Edit view & Export artifacts after 14.4.1 Update (AMD-only) (affects Cr, LrC & LrD)

[hyund39164868]

Hi,

Since just now, I've been experiencing a weird bug / crash in Lightroom Classic (on a Mac), where ALL my photos suddenly are fully covered in artefacts in the Develop module.

When I check the linked RAW + JPEG source files in Finder, they all seem ok (they don't look corrupted, nor show any artefacts here), meaning the issue is within Lightroom.

When I export images out of Lightroom (with any setting, edited or even not edited), the artefacts are also present on the export files.

This problem started occuring soon after I applied the new AI noise reduction feature on just ONE (1) photo. 

I already tried:

• Closing and re-opening Lightroom
• Shutting down (fully), and restarting the computer after 1 minute
• Switching the GPU accelrator setting in Lightroom on/off

MY SPECS

• Lightroom Classic 13.0.1 - Build (202310121438-d2af310c)
• Macbook Pro 16" - 2019
• 2,3Ghz 8-core Intel Core i9
• AMD Radeon Pro 5500M 8GB 
• 32GB 2667MHz DDR4 memory
• OS Sonoma 14.4.1

Any help would be greatly appreciated, because this makes the whole software unusable....

Thank you!

@Aline_Alves1963 Please give us detailed informations about your system. 

Please provide a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

Without these infos we can't say more.

Aline, assim como muitos que postaram aqui nesse tópico, você deve estar usando umMacbook Pro de 2019.

Eu resolvi atualizando o sistema operacional para o Sequoia.

When I use AI noise reduction I get strange white or coloured squares on my processed picture. Any idea how to get this problem fixed please ?

As a first troubleshooting step, please do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set. 

There are known problems with some older Macs, but we need to see the System Info first.

Apple released buggy graphics drivers for the AMD Radeon 5000-series GPUs, causing problems for many LR users.  You can work around issues displaying photos in Develop and Library and exporting them by setting Preferences > Performance > Use Graphics Processor to Off. But unfortunately, Adobe in its wisdom refuses to have the AI commands like masking, Remove, Denoise, and Lens Blur obey that setting (and Denoise would take 10 minutes or more per photo). 

Many have reported that upgrading to Mac OS 15 solves the problem, but some have reported that it doesn't.
