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!

When I imported my photos, they were normal in Library Preview but when I switched to Developer Mode I got this crazy coloring on every image. It changes when I zoom it, but I can't get rid of it. How can I correct this?

Most likely you're on an Intel Mac with an AMD Radeon 5000-series GPU. If you're not, then do the command Help > System Info and copy/paste its entire output here.

Apple released a buggy graphics driver for it in Mac OS 14.4.1. Most people report images covered with static-like noise but a few have reported problems with LR's AI commands.

Users experiencing noise and artifacts can often work around the problem by restarting their computer and/or setting Preferences > Performance > Use Graphics Processor to Off.  But for problems with AI masking caused by the buggy driver, you're out of luck: For some inexplicable reason, Adobe refuses to allow users to disable use of the GPU by LR's AI commands.

Adobe says they notified Apple months ago.  There have been a few reports that updating to Mac OS 15 (Sequoia) fixes at least some of the issues.  If you try Mac OS 15, please let everyone here know whether or not it works.

Spot on! A good old-fashioned restart seems to have corrected the artifacts, which're no longer showing. Thank you for your fast response~
