A short while ago, I updated to Kubuntu 20.04. And with the OBS distribution not supporting 20.04, yet, I installed the flatpak version instead.
Initially, I had some issues with the lensfun database being out of date, but we found a workaround for that.
Also, my OpenCL stack (rocm) would not compile in the beginning, but this has since been resolved. But when starting a development version of Darktable for a different reason, I noticed that the Flatpak version does not seem to pick up my OpenCL stack, whereas the development version and the stock-Ubuntu version does.
Does anyone know why the Darktable Flatpak does not find the rocm OpenCL library?
