I'm just getting started with Darktable 3.0.0 processing some RAW files out of my Canon 6D MkII.
One odd thing I noticed is that some of the modules seem to create hot pixel-like "sparkle" artifacts when using them. Here's an example:
This particular example comes from using the "Haze removal" module and pushing the strength upwards. Below about 0.10, they seem to disappear, but I've not checked everywhere. I've also seen this using the equalizer module. These artefacts persist even when exporting to PNG or JPEG.
Is this a bug? Or am I using it wrong, and it's an artefact of something else?
