When I open my raw files (from a Canon T5i) in rawTherapee there is an incredible amount of false noise. But In darkTable the images look fine. Am I missing a step here? To me it looks like an issue with demosaicing.

I read Editor - RawPedia , but I beleive the difference is way too much to explain by anything in that section.
