P: ACR 18, LrC v15.0 & LrD 9.0 Landscape masking does not work

[javierv82750378]

Landscape AI masking does not work in LRC V15. After a while no mask is generated nor displayed.

Using latest W10 64 version, i7 with 32GB RAM,  Nvidia Quadro p620 with latest drivers (DirectX V12) and latest LRC process (V6). Everything worked fine until the update.

Have tried disabling graphic card and same results. Any clue ? Is that happening to someone else ?

[namitche]

Can anybody tell me what I'm doing wrong.  I'm on lightroom desktop and updated to version 9 today but my landscape mask won't work.  It just keeps saying detecting and then goes away.  I"m relatively new so could be user error. Thanks.

Hi @namitche, welcome to the community!
Could you share a bit more about what’s happening? Does this occur with every photo or just specific ones? If it’s only certain photos, what file format are they? Also, if you can share a screenshot or a quick screen recording of the issue, along with the version of macOS you’re using, that would really help us investigate further.
Thanks so much!
Alek

Moin,

Ich habe vorhin die neuste LR-Classic Version installiert.

Lightroom Classic-Version: 15.0 [ 202510171722-44f87028 ]

Die Benutzung der Landschaftsmaske führt zu einem Treiber-Timeout(AMD -RX Vega 11).
Danach lassen sich andere Masken auch nicht mehr erstellen

Nach Neustart von LR-Classic lassen sich alle anderen Masken erstellen und funktionieren einwandfrei, sobald aber Landschaftsmaske ausgewählt wird wiederholt sich das oben angeführte Phänomen.
Das passiert unabhängig davon, ob Grafikbeschleunigung aktiviert ist oder nicht.

First thing to try is to make sure you have installed the most current GPU driver.

If that doesn't work, you are working with an 8 year old GPU, and it may be that this old GPU cannot handle the task properly.

Hi @Axel HH

Sorry to hear about the experience. I agree with the suggestion to update your GPU drivers, shared by @dj_paige.  More detailed GPU troubleshooting steps are shared here: https://adobe.ly/3LhNpIM

If that doesn't help, to help us investigate further, could you please share the following details:

• Your System Info (go to Help > System Info in Lightroom Classic and copy the details here)

• Whether the issue occurs with all images or a specific one

• If you’ve tried resetting Lightroom Classic preferences yet, if not, do give it a try. Here’s the link to the official guide for resetting preferences in Lightroom Classic:
  https://adobe.ly/4hCBKAD

  Important: Please remember to back up the folders before deleting deleting them.

Let us know how it goes!

Regards,

Srishti

Hallo Srishti,

Ich habe alles durchgeführt.
- Treiber-Update
- Preferenzen zurückgesetzt.
Es passiert weiterhin bei jedem Bild, die Maskenauswahl "Landschaft" verursacht den Fehler "Treiber Timeout"
Alle andere Masken funktionieren.

Viele Grüße Axel

I also agreed with @dj_paige.

What happened if you switch off the GPU support from the Lightroom preferences?

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

Update: while checking preferences, GPU appears as disabled due to an error (not specified). I know it is a relatively weak GPU but it worked flawlessly in previous versions.

I've just upgraded to LR Classic v15 with odd (never seen before) behavior I've narrowed down to lansscape masking. 

When I invoke Landscape masking, there is significant delay and the program simply reverts to the develop panel as if I never tried to mask and NO mask was produced.  All other masking functions work correctly.  Additionally immediately after this happens, the GPU acceleration has been set to OFF and cannot be re-enabled until I rename the folder "Adobe Photoshop Lightroom Classic" (in: C:\Users\<user>\AppData\Roaming\Adobe\CameraRaw\GPU) then restart LR - when it defaults to "Auto".

When this happens, I cannot select any other image in the filmstrip...it stays on the image for which I attempted the Landscape mask.

I've tried the exact same procedure on the same image from PS/Camera Raw with the same result except this error comes up:

If I restart PS, the GPU acceleration is re-enabled (no files need to be renamed).

This error accurs on ANY image I've tried (over a dozen) and the images have clearly obvious landscape features.

Here's what I've done so far to no avail:

- Reset Preferences (multiple times)

- Uninstalled and reinstalled LR Classic

- Updated the GPU drivers to the latest (Twice)

- Completely re-imported all images to LR

My hardware has executed these functions all previous LR versions for the past 5 years.  Heres my LR System Info BEFORE the error:

Make sure you have the most recent Studio driver for your GPU. If that doesn't help ...

You have an 11 year old GPU, I'm not surprised that it cannot perform some tasks at all.

[Srishti Bali]

Hi @javierv82750378

Thanks for reporting this. Could you please share a few more details so we can look into this further?

• Does the issue occur with all images or only specific file types (e.g., RAW, JPEG)?

• Do you notice the same behavior when using Select Sky or Select Subject?

You may also follow the steps shared here https://helpx.adobe.com/lightroom-cc/kb/troubleshoot-gpu.html

Regards,

Srishti

[johnrellis]

"DirectX: NVIDIA GeForce GTX 970 (32.0.15.8157)"

That's the most recent driver (Nvidia doesn't provide Studio drivers for that GPU). Try installing an older driver, e.g. from August 12 or May 12:

https://www.nvidia.com/en-us/drivers/

Do a clean installation of the driver, as described in step 3 of solution 4:

https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html#solution-4

[JDBlock]

Thank you johnrellis...the direct links were very useful.  I tried various older drivers back to Jan 2025 (the oldest shown in the NVIDIA site), but to no avail. 

I appreciate your help.  It appears to be likely my GPU just ran out of gas for this version.  I reinstalled the previous version of LR Classic for the time being until I can upgrade my GPU.

Thanks again for your helpful suggestions and direction.

Hi. Sorry for the delay. I have only tried with Canon raws (CR3). Both Lightroom and ACR (18.0.0.2389) deactivate GPU due to irrecoverable error (?). After that, ACR masking (landscape, subjet and sky) work relying on CPU very slowly. In Lightroom after trying to use the same masks with GPU disabled, do not work either. Basically they do nothing. But if I use another mask like Object, it works and morer surprinsingly something is "unlocked" in Lightroom and Landscape, Subject and Sky all three work but again very slowly. Note that all this happens after GPU has been disabled in both LR and PS-ACR.

[javierv82750378]

Same behavior with jpgs in LR

[javierv82750378]

In LR after enabling GPU in Preferences and restarting, all three masks Sky, Background and Subject work, but Landscape stalls. Nothing happens, the GPU is disabled due to an error and LR Develop module freezes. It works again after going to Library and then back to Develop, but with the limitations I am explaining and GPU disabled.

[Baowherever]

Hey @Aleke , I have the same issue as Namitche since I recently updated to Lightroom 9.0 so I can answer some of your questions.

- This occurs with every pictures that I tried
- File is RAW

- Im on Windows 10

Before the update, the landscape detection mask worked fine but since, when I try, it freezes and find nothing. Then, as You can see in the video, the app doesn't work anymore, Im unable to use any mask like the brush. Im forced to restart the app

Thank you

[Sameer K]

Hey, @Baowherever. Welcome to the Lightroom Community. Thanks for adding the details and the video; it helps.

The original post is about the issue on macOS, and you're on Windows. We'll need more info to help you figure this out. 

Please share the system information from Lightroom Help > System info > Copy and paste into a text document > Upload and attach here. 

The issue could stem from outdated Graphics drives or unsupported hardware. Troubleshooting the Graphics device drivers can be the first step in mitigating the error you notice. Please follow the steps here: https://adobe.ly/4lW7zWn

Let me know how it goes. Thanks!

[Sameer K]

Hey, @javierv82750378. Thanks for sharing the System info and the updates.

Please follow step 6 in the content here to configure the default GPU for Lightroom: https://adobe.ly/49YQSCI

After updating the GPU drivers, try the steps below and check the results. 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)
• Launch Lightroom again.

Let me know how it goes. Thanks!

[javierv82750378]

Hi Sameer. I've tried to follow the step 6 of the link you kindly sent but it leads me to a page for checking GPU compatibility with PS (no step 6 found). Can you please check on this and send me the right link ? I've run the test however and this is the result (apparently all is OK). I'm sorry is in spanish, but all checked green.

[dj_paige]

Update: while checking preferences, GPU appears as disabled due to an error (not specified). I know it is a relatively weak GPU but it worked flawlessly in previous versions.

Just because it worked in previous versions of LrC does not mean this 7 year old GPU will work with the current LrC 15.

Please check the driver and make sure you have the most recent Studio (not Game Ready) driver for your GPU.

Hey @Sameer K 

Thank you for the quick answer. 
I attached the text document as requested. (Sorry for the french in the document).

I tried the different troubleshooting steps explained in the link you gave me. When I desactivate the "Use graphic processor" in the preferences menu, the landscape masking tool works fine. So I updated my NVIDIA drivers but it didn't change anything. The bug is still there if my "us graphic processor" is activated.

The problem exists only since a few days and my other masking tools are working fine.

Hi Sameer. I performed a clean NVIDIA latest driver install without success. After analyzing the log I sent you yesterday (see previous message) with error descriptions in both W10 and LR, I saw that there is a repeating  DirectX error: "DXGI_ERROR_DEVICE_HUNG (hr=0x887a0006): CreateCommandList failed" that Microsoft describes as:

"Badly formed commands sent by the application". That is on Windows side.

Then I was able to find a similar entry in this forum where the error on the LR side "dng_exception (200025) in cr_gpu_tile_render_task" was described in previous LR version with another GPU.

The related entry is in: https://community.adobe.com/t5/lightroom-classic-discussions/gpu-stops-working-when-trying-to-add-a-... 

The entry does not specify if issue was solved, but one of the possible solutions Adobe gave to overcome this problem was:

"Adjust Windows Graphics Settings:

Go to Settings > System > Display > Graphics.

Under "Add an app," select Desktop app and browse to the Lightroom Classic executable (usually in C:\Program Files\Adobe\Adobe Lightroom Classic).

Click on Lightroom Classic in the list and then click Options.

Set the graphics preference to High performance and save the changes. This ensures Windows is prioritizing your dedicated GPU for Lightroom."

I followed these steps and also activated the Hw accelerated GPU programming in Windows 10 (in W10 Graphic Configuration menu also). I never needed to implement these changes with previous LR versions, but this time Landscape mask did work with GPU enabled.  Much slower than before but at least it works.

I am pretty convinced something has changed in LR15 that is causing this behaviour with supported GPUs and expect you can find in short a solution and release an update to the product.
