Well, rustcl has not been concidered as stable so far. You might start darktable with ‘-d opencl -d verbose’ and share the log.
Nothing’s really there I think.

However, when I fiddle with Filmic and Color balance RGB modules that are causing image blackouts under Rusticl, there’s no output in the console. As noted previously, Rusticl has the same problem both in in X11 and Wayland.
