(Win11) Lightroom Classic Artifacts issue

[William28602309rgn6]

Having an issue that cannot seem to work thru.  I'm new to lightroom.  I started to use it in December 2022.  When I first got it it worked fine, no issues and I started to learn how to use it.  Then about mid February I started to see artifacts that looked like colored lines almost resembling a barcode appear in my images other times I see a large about of white dots that just showing up against dark areas.  I got with Adobe support and after a couple of hours they decided that the issue was my graphics card.  I had an RX550, so support said to upgrade my card and I should be good.  So I ordered and installed a new Nividia GTX 1650 graphics card.  Nothing changed, same artifacts as before again back online with support, this time we uninstalled lightroom and reinstalled it.  Again no change.  I'm running windows 11 on a Dell Optiplex 7090 with an i7 processor and 16 GB of RAM.  I have had some fellow photographers tell me to just buy a Mac Mini computer and that should fix the issue, but I would rather not if I don't have to.  Has anyone else ever had this sort of issue and if so how did you correct it.

Hey @William28602309rgn6. Welcome to the Lightroom Community. We'll need more information to help you figure this out. Could you please share the system info of Lightroom Classic from Help > System info > Copy & paste into a text document > upload and share with us here?

I've looked up the case records & some troubleshooting steps have been tried. Artifacts could be caused due to faulty cables & other hardware misconfigurations. You've moved from a Radeon RX550 to Nvidia GTX 1650. A proper deep clean-up of existing drivers & clean install of Nvidia drivers are much needed.

1. Set the default GPU for Lightroom following the steps here: https://community.adobe.com/t5/photoshop-ecosystem-discussions/set-up-gpu-for-high-performance-in-ph...
Instead of Photoshop.exe & Sniffer.exe > Go to Lightroom Classic's installation folder & use Lightroom.exe.

2. The GPU info & Logs location on Windows is %APPDATA%\Adobe\CameraRaw. A shortcut to get to this folder on Windows is:

• Press the Windows + R
• Enter %APPDATA%\Adobe\CameraRaw
  
  
• Rename the GPU & Logs folder in this directory by adding .old at the end. (GPU.old & Logs.old)
• Restart Lightroom Classic, which should capture the updated driver & hardware capabilities.

Let me know how it goes. Thanks!

It would really help if you showed us a screen capture of these artifacts. Use the "Insert Photos" button, do not attach files.

It sounds like you have either corrupted files, or a problem with the GPU. Try turning off the GPU in Lightroom Classic (Preferences->Performance->Use Graphics Processor set to off). Does that make a difference?
