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.

Summary:

We can still not replicate this failure on test or production machines at Adobe. This appears to occur on Lightroom 12.4/Camera Raw 15.4 and later on very old Macs (8 Years and older) and is likely due to out-of-date video drivers on no longer-supported or updated GPUs.

The issue manifests as visual color artifacts in the Develop view only but doesn't always appear on exported images. It can also manifest as less-than-black deep shadow areas.

This option:

1. Update to LR 13.1 and set Preferences > Performance > Use Graphics Processor to Off. Most people with this issue report that works for them. (It won't work on 13.0 through 13.0.1).

 

 

so far seems to be working for me 🙂

I've read most of the threads on this topic, and I'd like to report my problem also.

 

- I've been using LRC v12 and MacOS 12.6.3 for a while - everything was fine;

- I've decided to try LRC v13 with MacOS 12.6.3 and had all those issues mentioned;

- Downgraded to LRC v12 back again, and problems were solved;

- I've updated the system to MacOS 12.7.3 and now my LRC v12 is also having the same issues on the low light areas.

 

It corrects if I turn off the Graphic card on Performance menu. But then I loose zoom shortcuts which I'm addicted (shift+mouse). I haven't tried the calibration v4 yet. But funny enough sometimes this problem auto-correct itself. I haven't figured out what I've done differently to bypass this issue.

 

here is my system info:

I just hope Adobe can make a fix for that! I guess many people are having those issues. And I work with a catalog with more than 180.000 images...

Hi!, I have a problem with my display. Gray highlight appears whenever I adjust my shadows and blacks. There's no problem when I export it. I just want my photos appear without the gray highlight in loupe view. The gray highlight disappears when I change my process version to version 1 or 2 in settings menu.

A possible cause could be a defective monitor profile.

"Probably a problem with my graphics processor [AMD Radeon HD - FirePro D700]. I'm using Mac Pro (2013), Monterey 12.7"

 

AMD stopped providing driver bug fixes for that graphics processor a couple years ago. LR is very sensitive to driver bugs.

See this post for LR Classic workarounds:

Similar workarounds for LR 7.2 will probably help.

SOLVED: If you have AMD Graphics on your intel Macbook Pro, just restart your computer and it will fix it. Recent drivers have this problem. Not only in Adobe apps. Even my Spotify album artworks looked like that. This starts to happen after usage of Lrc. I wasted hours for installing different versions of Camera RAW and Lrc. However, the solution was to reboot my computer. I refuse to turn of hardware acceleration on Lrc. I heavily rely on the new Denoise (Enhance) feature of Lrc.

Turning off the GPU acceleration in Lightroom preferences does not disable it for AI enhance. In fact you can't turn off the GPU for the AI features. The toggles in preferences only apply to the camera raw pipeline and to acceleration of the display. The way to circumvent the problem entirely without having to reboot regularly appears to be to turn off all the acceleration except for the display acceleration. That will still allow you to do the AI enhance and all the AI masking works just fine.

Hi community, I have been transitioning from Lightroom to Lightroom classic and have an issue when displaying my photos, sometimes which actually is quite often now there is a weird color comes out on the photos which really distracts from any edit , it's like colour noise, sometimes blue, purple , yellow ets. I don't have histogram flags on and I have turned off show clipping and it's still on . In times it disappears but then comes back again, any idea how to fix it ? I really want to use class to improve my edit but it makes it so frustrating! 

thanks in advance

You will find a long forum thread on a topic that looks similar to yours-

Here- Colored "pixel" artifacts   where John Ellis gives answers like-

"Since the previous messages were posted, it's come out that versions LR 12.4 and later have an incompatibility with older Macs with graphics processors whose drivers are no longer supported by their manufacturers:"

This would be worth investigating.

 

Regards. My System: Lightroom-Classic 14.0, Photoshop 26.0, ACR 17.0, Lightroom 8.0, Lr-iOS 9.0.1, Bridge 15.0.0, Windows-11.

Don't expect any help from Adobe on this other than continuing to charge you a monthly licence fee for software they didn't test properly that they claim runs on the minimum specs of older Macs.  You have 3  options

 

1 - Regress to an older version and keep paying your licence for zero updates

2 - Disable using the graphics processor in preferences > performance (works for some people but makes things slower)

3 - Buy a new Mac

 

I ended up doing 2 then 3.  My preferred option would have been for Adobe to release a one off payment version for the last good version as many, many people were impacted.  They have acknowledge the problem as I had several calls with their devs then thing just went quiet with no emails replied to.  Not a great customer experience.

This is happening for me, and gets resolved when I disable the GPU, which is of course not at all preferred.
