@rbrixel
Can you open a cmd.exe and start darktable with - - disable-opencl and report back, what happens, pls?

[rbrixel]

I used the following command from non-admin cmd:

C:\Program Files\darktable\bin>darktable --disable-opencl

...and it works! Should I create a desktop link with the command?

Edit:
I added the command "--disable-opencl" in the windows startmenu entry. Now it starts even from cortana :)

[AxelG-DE]

@rbrixel
I wouldn't say so. That was just to figure, opencl might be your culprit.

Opencl is useful and we should get it to work for you.

There is lots of questions possible from here but today I need to keep short...

Me I'm running Linux, so I'm afraid I cannot help to all extend and also the handbook does not refer closely to Windows...

Can you pls. self study here https://darktable.gitlab.io/doc/en/darktable_and_opencl.html
(while I gotta sleep now :smile:)

[AxelG-DE]

@ClaesGitHub
Do you have some good hints for @rbrixel?

@rbrixel, it would be interesting to:

• "darktable -d opencl" on a cmd.exe and paste the output here
• knowing the GFX board & driver
• seeing darktablerc

As this is likely not a bug, the devs (l'm only a user) may want us to move to pixels.us forum?

[ClaesGitHub]

Moinchen!

I agree with AxelG-DE: _As this is likely not a bug, it might be wiser to move to pixels.us forum_
In the meantime, check this info:

[rbrixel]

Okay, Windows did not update my drivers automatically. Not even if I manually searched for updates.
I had a graphics card driver installed in version 17.x. Now I have the current version 19.5.1 "Adrenalin 2019".

Now it works without the flag "--disable-opencl".
It was up to the graphics card driver. Damn.

A big thank you to everyone!

Also had the same issue with a ryzen processor and Windows 10, but updating drivers seemed to fix the issue
