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.

(Screengrab from the Develop module in Lightroom Classic)

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.

(Screengrab from the RAW source file in Finder)

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

(Screengrab from the exported JPG image)

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!

Reports are coming in about this happening in camera RAW as well. I've had it happen on a 2019 MBP in ACR, fixed by restarting the computer. I suspect running low on RAM/VRAM but I don't know.

"Metal: AMD Radeon Pro 5500M"

That's a five-year-old GPU, relatively old in GPU-land. There have been lots of reports in the last year or two of LR problems with older AMD GPUs on Mac and Windows. Most likely these issues are caused by bugs in the AMD graphics drivers. Unfortunately, on Mac you have to wait for AMD to supply a new driver to Apple and then for Apple to release it in a new version of Mac OS.

So disabling or partially disabling the GPU is the only option in the short term. Note that if you observe bad symptoms with LR's AI commands (AI masking, Denoise, Lens Blur) disabling the GPU in Preferences won't have any effect -- Adobe doesn't allow the GPU to be disabled for the AI commands.

My work MBP has a Radeon 5300M card. So yeah its entirely possible that the latest driver update is having issues.

Thanks for sharing the link to the earlier post. I suspect my MacBook is the problem, and this might just give me the justification to buy a new one 😉

Thanks, I turned it off and will monitor if it happens again. I posted my system info in my reply to @John R Ellis 

[John R Ellis]

"Metal: AMD Radeon Pro 5500M"

Some of those other reports are for the 5500M and 5300M. It could be that the recent release of Mac OS included a new (buggy) driver from AMD.  

In the other thread, the poster observed that setting Preferences > Performance > Use Graphics Processor to Custom / Use GPU For Display worked around the issue. That's likely to be somewhat faster than setting it to Off.

[John R Ellis]

Moderators, @Rikk Flohr: Photography, please merge with this thread describing similar symptoms with the same Mac / AMD Radeon 5500M GPU:

https://community.adobe.com/t5/lightroom-classic-discussions/artifacts-on-all-photos/m-p/14582228

[F. McLion]

Will do so and mark the other as primary

[Jao vdL]

What mac are you on and did you recently update the OS? There have been reports on similar artefacts after updating to Mac OS 14.4.1 on older intel Macs with ATI GPUs.

[Jao vdL]

Example here: https://community.adobe.com/t5/lightroom-classic-discussions/p-artifacts-on-all-photos/td-p/14563606

Restarting fixes it for some people for a bit. APparently this is due to the GPU running out of memory.

Hi, I am having problem with my Lightroom Classic in Develop mode. This is what I am seeing when the file is in Develop mode, but okay in General. Please help me how to solve this issue! TIA! 

(Am using Mac)

[moved from bugs to discussions according to the community rules - Mod.]

Please try if it helps to deactivate the GPU acceleration.

Also, please post the system information found in the help menu.

And, let us know the source of the image (camera, file format - raw, jpg ...)

Your issue is almost certainly the same as described in https://community.adobe.com/t5/lightroom-classic-discussions/p-artifacts-on-all-photos/td-p/14563606

Both yourself and and the OP in linked thread are using Mac with an AMD Radeon Pro 5500M GPU.  There are other posts with the same issue and same GPU model.

[Erin3703332070t7]

I uploaded a new set of photos on Lightroom today and all the photos uploaded with this weird matrix-looking glitch. I thought it was an issue with the memory card. But I went through old photos and they all have it as well. I reuploaded the photos, I also uninstalled the app but that didn't fix the issue either. The app is the latest version and it is on my macbook pro. Any help would be great!

[John R Ellis]

Building on Ian's reply, another user in that thread reported that setting Preferences > Performance > Use Graphics Processor to Custom / Use GPU For Display worked around the issue. That's likely to be somewhat faster than setting it to Off.

[John Krajec]

So… i updated MacOS to 14.4.1, and Lightroom Classic to 13.2, now when I export I get digital noise distortion. Has anyone else seen this problem, or what's going on?

Thanks,

JK

[John Krajec]

I tried LRC 13.1, same results -- meaning there's still noise, but different patterns each time I esport. 

[John Krajec]

after (anther) reboot it appears to be working. 

Sorry for the trouble.

[Jao vdL]

It might come back. Apparently since mac os 14.4.1 there is a bug in the driver for certain older video cards that causes the GPU memory to fill up and this has the effect you're seeing here. If you have an older intel Mac that might be the issue.

[Ian Lyons]

Does your Mac use an AMD Radeon GPU? If yes, then can you indicate which model and the amount of VRAM.

[John Krajec]

Thanks to both of you. That does make sence. It's hard to say my 4 year-old computer is old, but yes, I know the drill!

It's a 2019 16" MacBook Pro (8tb/64g ram, 2.4GHz 8-Core Intel i9), AMD Radeon Pro 5500M 8GB / Intel UHD Grapics 630 1536 MB

Things were working fine on MacOS 13.4 I think it was… but did both OS and LRC upgrades at the same time so didn't know which was the culprit. 

So far so good, but will post when (if) things start acting up again.
