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!

Thank you for the tips. I will implement them and see how they work.

@ozulrike, "So far, the issue has not occurred again. "

Did you change the setting of Preferences > Performance > Use Graphics Processor or just restart LR?

[ozulrike]

I swtiched the GPU accelerator off.

I'm having the exact same problem, but it happens about half way through editing a set of 100+ images

Hello. I was working with lightroom and suddendly all photos in develop mode turned to show like this. How can I fix it? Photos like this is just in develop mode, in library they are normal

[Ian Lyons]

Your screenshots and given that you're using a Mac, then I suspect your issue is the same one described in this bug report https://community.adobe.com/t5/lightroom-classic-bugs/p-gpu-develop-edit-view-amp-export-artifacts-a...

If you could submit a copy of your 'System Info', which can be obtained from the LrC Help > System Info menu item, we would be better placed to confirm that you've been bitten by the above linked bug.

Anyone know what is causing my Lightroom CC to glitch like this and how to fix it?

 

[Bill Sprague]

Without knowing more about your system, I'll guess that your graphics card or screen are failing.  It may also be a graphic card driver that needs updating.   To me, that does not look like a Lightroom failure.

[Cristina@AMTL]

Thanks for responding. 

My laptop specs:

Apple 2019 MacBook Pro (16-inch, 16GB RAM, 1TB Storage, 2.3GHz Intel Core i9)

I am seeing it happen quite a bit in the wedding photography groups I am a member of. I will go find the minimum requirements for LRCC

[Cristina@AMTL]

Maybe this is more helpful?

Graphics Card Description Dedicated

[Rob_Cullen]

Consider also it may be a camera problem.

I also have seen a similar fault appear in files from a (point & shoot) camera that was used in very cold conditions. (4 degrees C).

If working to check the Graphics card drive is not successful, you might access a friends system of Lightroom, to test the image files there.

[Ian Lyons]

Given the artefacts you're seeing plus the computer model and GPU, then there's high probablity that you're seeing the same bug as detailed at https://community.adobe.com/t5/lightroom-classic-bugs/p-gpu-develop-edit-view-amp-export-artifacts-a...

[John R Ellis]

Cristina@AMTL, 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.

Cristina@AMTL, "Metal: AMD Radeon Pro 5500M"

As suspected, your Mac also has an AMD Radeon Pro 5500M graphics processor, which is one of the culprits causing these symptoms. So you'll need to use one of the workarounds:

[Cristina@AMTL]

I will give it a try. Thank you!

Hello, when I using mask, any if them, Lightroom can't find any. For example I choose to select  people, sky or backround, lightroom writes that it can't find it, but earlier everything was Ok.

I also have issues with gliched images bug, I am using mac. I can work only with GPU turned of, but then some funcions are very slow

Mac OS 14.4.1 included a buggy driver for the AMD 5000 series GPUs. Many people are tripping over this issue and Adobe has said they're working with Apple and AMD on it.

For the glitchy images, others have reported two workarounds: 1) Restart LR when the glitches occur or 2) Set Preferences > Performance > Use Graphics Processor to Off.

For problems with AI masking caused by buggy drivers, 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.
