Huston, we have a problem

RL output sharpen is not an option that is available by default. Must be a LUA script/plug-in/add-on. Does the error still happen when you disable this one?

That might be a good idea. Just in case this is a camera (type) specific thing.

???

Why do you say this, because darktable does benefit from it. Very much so. This is what the dtdocs have to say about it: opencl

I went from an old NVIDIA graphics card, not opencl capable to a capable NVIDIA card and the positive difference was huge!

I also tried to replicate this issue you are having and was not able to (both 3.6.1 and 3.7.0+1537).

I have an amd ryzen 7 with renoir.

dt opencl will not work according to the doc and my own findings:

Thanks
