P: Denoise - large artifacts with AMD Graphics Card

[SSGT_BARNES]

When I use Denoise on RAW images, the images are putting strange squares on the DNG once it is created.  this was after the latest update on both mac and adobe lightroom.  I've spent HOURS on adobe customer service, don't know how to fix this.  I love that feature.

 

 

[SSGT_BARNES]

Nobody knows?

Please post a system report for us, we have no technical info to go by here. Help->System Info

[SSGT_BARNES]

None of this artifacting happend before the last update to mac os and lightroom 

[Lumigraphics]

I just had a weird issue where Camera RAW was showing me a distorted preview but rebooting fixed it and Denoise is working fine now. 2019 Intel MacBook Pro w/Radeon card.

[SSGT_BARNES]

The denoise is coming from the AI feature.  Something I think is far superior to regular denoise.  (if thats what you are refrencing). I have tried everything under she sun.  Its a bug they have going for sure.

[Lumigraphics]

You mean Enhance.

[SSGT_BARNES]

Yes Enhance...  Great feature it just stopped working after all updates.  It seems like it is having trouble making DNGs...

[Lumigraphics]

Its working fine here. Try resetting Camera RAW preferences maybe?

[SSGT_BARNES]

In lightroom?  What suggestions might you have as far as settings?

[stephaniepepper]

I recently updated to the latest version of LR classic. Today two photos I've used denoise on have ended up with a square in the photo. Attaching images for clearer idea of the issue. Nothing has changed in my workflow other than the recent update. Using iMac macOS

So you have the latest LR and the latest Mac OS and thus the latest graphics driver for a four-year-old graphics chip with enough graphics memory.   

These symptoms could be caused by an incompatibility between LR 13.2 and the graphics driver (Adobe is frequently changing the code that uses the GPU, and AMD has been having bugs in its latest drivers). Or it could be a hardware issue somewhere between the memory card and your computer. 

To start narrowing down the cause:

1. Upload one of the problem raw files to Dropbox, Google Drive, or similar, and we can see if the issue occurs on other LR installations.

2. Temporary roll back to LR 13.0. If the problem no longer occurs, that's suggesting a problem with the AMD driver in Mac OS 14.4.1. 

[stephaniepepper]

Ok, I think I'm doing this right. If not, please let me know. This is one of the problem files.

I do not currently have a MAC, my rig Windows, and not AMD GPU (NVIDIA in my case). (note that I used to have a MACBook, but...)

But, testing  your sample on my rig, I do not have the issue you posted . LrC 13.2

Hopefully a member with a MAC, can test. Especially if they have a similar rig in CPU, MACOS, and GPU.

[johnrellis]

With your sample .nef, I successfully applied Enhance > Denoise four times with varying values for Amount, and there were no artifacts. (LR 13.2, Mac OS 14.4.1, Apple M2 Max).

This suggests the problem is not in the file but with your computer, likely a memory problem or a bug in the Mac OS 14.4.1 graphics driver for your GPU.  Suggested next steps:

1. Run hardware diagnostics:

https://support.apple.com/en-us/102550

2. I'd bet a little bit more on a buggy graphics driver -- recent AMD drivers have had bugs tripping up LR.  Since Adobe is constantly changing the LR code that uses the GPU, you might try rolling back to an earlier version of LR (see my previous reply), e.g. LR 13.0, to see if the issue still occurs.

Unfortunately, on Mac the only way to update the graphics driver is to wait for AMD to provide a new one to Apple and for Apple to release a new version of Mac OS.

[stephaniepepper]

Thank you so much! Given that I updated Lr and OS within days of each other, and had successfully used denoise since it came out without issue, my guess is that your bet is correct. I'll roll back Lr and see if that helps. Thanks again!

[Crisbasan0D4D]

I have the exact same problem, yesterday I was working with an Adobe consultant 3 hours online, he tried everything, but the problem was not solved. He said we must wait for another updates on Lrc and Camera Raw from Adobe. The denoise feature in Lrc and Camera RAW was working excellent until 2 weeks ago, before the latest Adobe updates.

[SSGT_BARNES]

I basically hd the exact same experience they called me back and said wed have to wait until the next update.  I also am having issues with other adobe programs involving enhance.   So they need to see what they did and fix it.  

[johnrellis]

Another person reported similar artifacts with an AMD Radeon Pro 5300 with LR 13.2  / Mac OS 14.4.1 after updating both LR and Mac OS.  The sample file didn't exhibit the artifacts when processed on my own LR 13.2 / Macbook M2 Max / 14.4.1.

This is looking like a a bug in AMD's graphics drivers. AMD's recent Windows drivers have had bugs tripping up LR, and it may be that recent changes in LR's use of the GPU is tripping over them. 

Since Adobe is constantly changing the LR code that uses the GPU, you might try rolling back to an earlier version of LR (e.g. LR 13.0), to see if the issue still occurs.

Unfortunately, on Mac the only way to update the graphics driver is to wait for AMD to provide a new one to Apple and for Apple to release a new version of Mac OS (a downside of Apple's walled garden).

Moderators, @Rikk Flohr: Photography, please merge with this thread describing similar symptoms on similar hardware/OS:

[Lumigraphics]

I've gotten a few instances of intermittent garbage in the ACR display on Sonoma/Intel with the 4GB Radeon 5300M, and one instance of Enhance/Super Res creating plain white DNG files from small TIFFs. Rebooting the computer has fixed this each time its happened. I suspect memory issues.

I'll do a bug report if it happens again.

[Steve Gandy]

Has anyone seen this?

 The posted image is a jpg but it shows up everytime when we do Enhance with Noise Reduction to a Canon RAW .CR3 file. The boxes are in random locations, sometimes white sometimes pixelated with colors.

It started out of the blue. I plan on replacing the catalog with a recent backup.

v13.2 on a current Mac

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.

Others have recently reported very similar symptoms that started with LR 13.2 / Mac OS 14.4 on Macs with AMD 5300 and 5500 GPUs. See here for details, possible cause, and a possible workaround:
