  1. Open canon .cr2 raw file as smart object from Lightroom.
  2. Double-click on file to open Camera Raw.
  3. Light Panel:
    1. Make adjustments to Highlights, Shadows, and Whites.
  4. Optics Panel: 
    1. Remove chromatic aberration.
    2. Use Lens profile corrections.
  5. Click OK.
  6. Add Clarity and dehaze adjustment layer.
  7. Either adjustment causes darkening of the image and creates blocky areas with different kinds of artifiacts.  It is nothing like Camera Raw Clarity or Dehaze.

    It seems that’s a issue with your graphic adapters. 

     

    ...    

    Device 1
    Name:                         Intel(R) UHD Graphics 770
    ...      

    Vendor name:                  INTEL
    Driver date:                  2025-12-01  000000.000000-000
    Driver age:                   2 months
    Driver version:               32.0.101.7082
    Supports UMA:                 SUPPORTED
    D3D-ID:                       18048
    ...

     

    This indocates that you've buildin a CPU with an integrated Intel graphics processor and it's enabled. Adobe recommends disabling second GPUs, as described in steps 5 and 6:

    You can also try to configure the settings so that Photoshop use the external GPU

    This was taken from Google’s Ai overview:

    Step-by-Step Instructions:

    • Configure Windows Graphics Settings (Recommended Method):
      • Right-click on your desktop and select Display settings.
      • Navigate to Graphics (or Graphics settings).
      • Under "Custom options for apps" select Desktop app and click Browse.
      • Locate your Photoshop.exe file (usually C:\Program Files\Adobe\Adobe Photoshop <version>\Photoshop.exe).
      • Click on the app, select Options, and choose High performance (your NVIDIA card).
      • Click Save.
    • Configure NVIDIA Control Panel:
      • Open the NVIDIA Control Panel.
      • Go to Manage 3D settings > Program Settings.
      • Select Photoshop from the dropdown menu (or add it).
      • Set the "Preferred graphics processor" to High-performance NVIDIA processor.
      • Click Apply.
    • Verify in Photoshop:
      • Open Photoshop and go to Edit > Preferences > Performance.
      • Ensure the Use Graphics Processor checkbox is enabled.
      • Confirm that your NVIDIA card is listed under "GPU Settings".
    • Troubleshooting:
      • Update Drivers: Install the latest NVIDIA Studio Driver for the best stability.
      • Disable Integrated Graphics: If necessary, you can disable the integrated Intel GPU in Device Manager, though setting it to "High Performance" in Windows is preferred.
      • Restart: Restart your computer after applying these changes.

      Disabling the built-in GPU solved my problem.  I didn’t realize there could be a chance the two GPUs were interfering with each other. 

      I’ve been using computers since the IBM PC was first introduced, and it shows that old dogs can learn new tricks.  

      Thanks so much, AxelMatt.

      Well, it looks like I have spoken too soon.  After doing all the things mentioned by AxelMatt above, the problem still occurs.  

      I added Photoshop to the Nvidia control panel → manage 3d settings → program settings.  There was no setting for “Preferred Graphics Processor”.

      In addition, I have run two graphics stress tests: Superposition and Heaven; neither of which shows any problems with my T1000.

      I’m at a loss as to what to do next.
