P: Colored "pixel" artifacts/subdued blacks in shadow areas (older Macs) (also visible on CR)

[Andrej Michelcich]

I updated LrC to 12.4 yesyerday. Since then a number of pixels in multiple colors appear appear quite often on the image, mostly in the areas of blacks/darks and when using Tone Curve commands. It's similar to the red/blue pixels which denoted clipping in the areas of blacks/whites, but they appear in very many different other colors. Sometimes they disappear, or decrease, after actioning the commands again, sometimes they do not. Is anybody else facing the same problem which I encounter now for the vey first time after many years of use of LrC? Thank you in advance for your advise.

I upload some details, it is specialy into the shadow... between library and developpement

[Xavier33878373ucf9]

I find that : when the GPU is enable the pics looks perfect same into both library and develop...

Any idea why it is like this ? my computer and lightroom doesn't want to work together ?

Thx

[Xavier33878373ucf9]

Finaly, the problem without the gpu still there.

In lightroom not the classic one no problem... i've tryed to uninstall and install again, put the Camera Raw GPU Config.txt in the bin.... nothing new... os Monterey and lightroom with the last version... there is a big trouble shooting....

[Xavier33878373ucf9]

you know what, if think it is a big bug from adobe.

i install the previous version instead the 13 i've installed the version 12 and it is working much perfectly... running on monterey. thx adobe... fix the bug please

Hello, I've been having issues with color distortion (I think) while editing and exporting images in Lightoom Classic. It looks like there are histograms levels that show up automatically on the photo and won't go away. The only things that have worked to get rid of the distortion is changing the process from Version 6 to Version 5 or 4 under Calibration. Would love some help with this!

[Lisa4BOYS]

This is exactly what was happening to me!

[JesseBeerPhotography]

Hey there, just seeing if anyone else has experienced this issue before and if there is a fix. Colors look great while in Lightroom but after export the shadows and blacks are getting quite distorted. Below is an example as well as my export settings. Seems to of just started happening this week and I havent changed my export settings in probably 10 years so thinking maybe its a bug or an app update changed something. 

Any help is greatly appreciated

(image on left is in LRC and tight image on right is exported version)

The same thing is continually happening to me.  (I posted prior)  It's not consistent at all.  I'm seeing it more in the black tones and especially black and white images I make.  I turned off the GPU and it's still happening.  Adobe please help this professional photographer out!  It's my busy season and don't have time for this!!   Thanks, Teresa

[toto19]

Developp in version 4 (versus Version 6) of process seems better for me

[Lisa4BOYS]

Can you get Version 4 to synch or copy to each image aka lock in Version 4??

I can synch everything else.  I check of Calibration when synching.  It still reverts every image to Version 6 and I have to go in and chancge it to Version 4 on EVERY image!  ANd if i decide I want to make any other lats changes and have set to Verion $, it goes back to 6 and have to go reset to 4 again.  SO FRUSTRATING!!!!

[emiseri]

I have a problem with the pictures, namely it shows me yellow or cyan colored pixels in the deep tones in developing mode and also as JPEG after export.
Does anybode know why this happens?

[tdoggett]

My 2015 27" I-Mac runs perfectly - EXCEPT for this LR issue which makes editing impossible. I have been waiting for a fix. I hate to buy an entirely new machine for what seems to be a programming bug.

[Paweł2588117827o3]

Mac Pro 2013 - I also have this problem. Colorful artifacts in the shadows. During preview and on exported images.

[ryebread]

UGH. that machine is not that old. 

Now that we hear this, there is no excuse that it's only OLDER macs with outdated graphic cards!

Adobe, PLEASE HELP!!!!!!

We can't do our jobs!!!!

[ryebread]

What is the latest from Adobe on this?

I'm seriously considering jumping to C1 before I update a 2015 Mac PRO. It's $7k to get a new one.

Adobe, we need your help on this!

[defaultrel1fc87ysev]

At this point, your best bet is to go back to Lr Class 12.3 because it seems to be the last version without this impairment.  Some people have found that disabling GPU support also works, but apparently export ignores this setting and still uses GPU and thus can remain impaired.

If your catalogue has been upgraded and won't go back, save you metadata and re-import your images.  This will preserve some/most of your edits, but if you've used newer features from 12.4, 12.5 or 13.0, such Process Version 6 instead of Process Version 5 or lens blur or newer camera/lens support, these will be lost.  Hopefully many edits will survice.  You will also lose other things such as collections because these exist only in the catalogue.

[michaelk2309]

@tdoggett, xactly the same situation for me. I have an iMac 27" late 2015, which is great to work with. Now we are getting the message that the computer is too old and the graphics card manufacturers are no longer updating drivers. On the other hand, I'm currently planning to buy a new Macbook Pro M3 so that I can work properly again. However, Adobe support still advises not to run Creative Cloud on Sonoma / OS14. What does this mean? I should downgrade the M3 computer to OS 13? Considering the prices Adobe is charging monthly, the product quality is downright ridiculous, not to mention outrageous. If anyone has an alternative suggestion to Lightroom - please post.

[Malcolm15C3]

Don't downgrade the OS.  Only one of the Apple M3 MBPs ever shipped with Ventura (specifically, 13.5, not an earlier version of macOS 13).  Our IT department once put their standard image on my new MBP, only it was an older version of OS X than the system initially shipped with and some things didn't work, performance was bad and it crashed a lot due to missing drivers or other incompatibilities.

[daveRedShed9UK]

I'm starting to look for alternatives now. I would hope there will be a significant rebate on what we are paying while this is going on

[michaelk2309]

even if my question about the downgrade was meant ironically - many thanks for the useful hint, Malcom!

[John R Ellis]

"Some people have found that disabling GPU support also works, but apparently export ignores this setting and still uses GPU and thus can remain impaired."

Specifically, due to a bug Export in LR 13 ignores the setting of Preferences > Performance > Use Graphics Processor and always uses the GPU. But LR 12 obeys the setting, so disabling the graphics processor in LR 12.5 will fix both the display and export problems with artifacts.  LR 12.3 is the last version in which people with this problem can enable the GPU.

[Jao vdL]

However, Adobe support still advises not to run Creative Cloud on Sonoma / OS14. What does this mean? I should downgrade the M3 computer to OS 13?

Not sure why they would say that. Lightroom Classic runs just fine on Sonoma and as far as I know there are no known incompatibilities with anything in creative cloud. You really do not want to downgrade an M3 machine as already mentioned. 

[Addygurl808]

Every time I am in lightroom of the development module, from time to time while editing the images become sprayed with a display of colorful colors. I do not know how or why it happens. I try to click on other images and then it transfers to the next. it takes time from clicking around to it finally disappearing. but then it always comes back from time to time. please help. 
LrC 12.5
macOS Big Sur 
Version 11.7.10

[Lisa4BOYS]

You have to change the calibration back to version 4 for EVERY image. SO
time consuming! Reach out to Adobe!!!

My temporary solution for Mac Pro 2013:
1. Remember Lightroom
2. Install v. 13.0
3. Use of a graphic processor = OFF

Thanks to this, I could use the catalog in the latest version.

Attention.

If you have to go back to version 12.xxx - write all changes to XMP files before. Because you will have to create a catalog again, but you will not lose work on processing.
