Hi, I am currently facing an issue where the red channel of imported images in darktable contains corruptions (black areas and ghost images) when i use "standard color matrix" (camera raw) or "embedded matrix" (dng file). Color profiles like Rec709 work as expected. Also converting the raw file using dcraw and importing the resulting tiff in darktable (sRGB color profile) works fine. I already made sure that dcraw and adobe_coeff.c of darktbale use the same color matrix for my camera, so I expected similar results. I cross checked with dcraw, rawTherapee and my camera manufacturers raw software - all show the picture as expected, only darktable shows corruptions.
What would be the best place to discuss this issue? Attaching huge raw files to a mailing list might not be the best option, I guess. Should i open a bug report for this? Currently it seems to me as if darktable somehow handles color matrices differently from all the other programs, but I'm not an expert on this topic. Maybe I am missing something critical?
