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!

Hi,

I've tried restarting my computer, creating a new catalog, and checking multiple sessions from multiple memory cards and my photos are importing like this into Lr. Started happening out of nowhere. Any advice?

Can you provide us with some specs on your Mac? (GPU Card? GBs?, Processor)

Hi Rikk, Hannah Nicollet found another post that helped me figure it out:

Just tried using LR Classic's new "AI Denoise" feature for the first time, and this was the result. Can anyone explain????

Likely a GPU issue: https://community.adobe.com/t5/lightroom-classic-discussions/p-gpu-develop-edit-view-amp-export-arti... 

Do you have a system like this?

@djinniferd: "2020 iMac running Sonoma. ... AMD Radeon Pro 5500 XT 8 GB"

Mac OS 14 (Sonoma) included buggy graphics drivers for the AMD 500- and 5000-series graphics processors, and as you can see in this thread, many LR users tripped over this. Upgrading to Mac OS 15 fixed the symptoms for most of the people in this thread, though reports continue to trickle in from a much smaller number of users of some glitches remaining.

Your Mac supports Mac OS 15:
