All images in all phases of darktable pixelates periodically about darktable HOT 12 CLOSED

Can you provide a log file (in txt or pastebin) of darktable-cltest?

from darktable.

Where do I find the log?

from darktable.

This is the worst error I have seen. Apparantly it is not pixelation, but parts of the image repeated in the wrong places.

from darktable.

Where do I find the log?

You will need to run darktable-cltest from the command line, where you will see the output of the command. You can copy the output from the command line window, or you can redirect that output to some file and attach it here.

Can you confirm that this problem does not occur when working with OpenCL disabled?

from darktable.

The logs the debug and log files are explained in the FAQ. https://www.darktable.org/about/faq/#faq-windows-logs

I'm not sure this is an opencl problem, but the log can help use. Another aid would be a log from -d common.

from darktable.

Thanks a lot. The output of that command:

Datktable found 2 GPU cards/drivers. Your description above list only one. How many do you have? Could you have two drivers installed on windows?

from darktable.

Yes - I have a small diminutive GPU on the Motherboard. But I need to use the AMD 6700 AX. (Both in Windows and in Darktable).
How do I select the right one.

from darktable.

You will need to edit the darktablerc file to switch that disable via value in h in the GPUstring. https://docs.darktable.org/usermanual/4.6/en/special-topics/mem-performance/#device-specific-opencl-configuration

from darktable.

I have no ideo how to edit this config file. In windows stored at C:\Users[user]\AppData\Local\darktable

In Device Manager, I have disabled the GPU on the motherboard. Should I then just uninstall, and reinstall DT for it to not get confused about GPUs? Are settings stored when I uninstall DT?

from darktable.

Use Notepad to edit the file. darktablerc is just a txt file. The FAQ explain this too. https://www.darktable.org/about/faq/#faq-windows-config

Uninstalling does nothing. All of configuration files remain in //AppData/local/darktable

An update.

Thanks gi-man. You took me on the right path. Everything is great now. Stable and no pixelations anymore.

The problem: I was simultaneously using 2 GPUs (one on mainboard, whose output is not used), and one on my GPU board.

The solution: In Device manager, I disabled the small GPU.

Results: Now I have no performance problems. And no pixelation.

Thanks a lot for feedback.
