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!

"Lightroom Classic 13.0.1"

Update to the latest version of LR, 13.2 by doing the menu command Help > Updates.

[caseyd49971034]

Mine is now doing this  same thing. Wondering if you found a fix? Mine is already updated to latest version. I'm stumped. 

[johnrellis]

@caseyd49971034, 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.

[hyund39164868]

Okay, so in the meantime I updated to LR 13.2. This didn't fully seem to solve the problem, altough the problem occured only on random times instead of all the time.

But, I've been trying some more things as well, and I think I found a solution now (@caseyd49971034 😞

• Go to "preferences" -> "Performance", and under "Camera RAW Cache settings": "Purge cache"
• Also, under "Performance": set "Use Graphics Processor" to "Custom" instead of "Auto", and then: only "Use GPU for display", and not "Use GPU for image processing".
• This, in combination with the upgrade to LR 13.2 seems to solve the issue for me.... (for now)

"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.

[Lumigraphics]

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

[ozulrike]

Recently, when working on photos in Develop mode, the image display does not work anymore and the photos look like abstract art. The photos show correctly in the Library. Closing and restarting LC does not solve it and I have to restart my MacBook Pro. I am running Senoma 14.4.1 and LC and the OS are up to date. 

Here a screenshot of how it appears. Any ideas of what causes it?

[dj_paige]

Try turning off the Graphics acceleration in LrC: PReferences->Performance->set Use Graphics Processor to OFF

If that works, you may have an old or malfunctioning GPU, or the driver could be bad.

Please tell us what make and model your GPU is.

[ozulrike]

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

[johnrellis]

"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.

[johnrellis]

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

[F. McLion]

Will do so and mark the other as primary

[johnrellis]

There have been a number of similar reports recently, all from Mac I think. As dj_paige suggested, 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.

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 😉

Following your advice, it has solved the issue. Thank you so much!!! 

[Lumigraphics]

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.

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)

Please try if it helps to deactivate the GPU acceleration.

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

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.

[johnrellis]

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.
