Strange artifacts when using local contrast module

I recently switched to an AMD graphics card Radeon RX 5700.

With this I get strange artefacts when I switch on local contrast module. This happens only when opencl is activated.


For activating opencl I additionally installed opencl-amdgpu-pro-pal, opencl-amdgpu-pro-comgr.
Do I need other packages for opencl to run properly?

Hmm…

Maybe it has something to do with this:

Do you get artefacts on this image only or on others too?

That’s exactly what I observe. I do have that issue with other images also…

I have the same problem with the same graphic card, on nearly all pics I use local contrast on.
