Hi Sebastian,
it has been quite strange working with these buttons in the "Create Image" window:
- I tried with a series of JPG pictures and, after the first time in which the status of the buttons seemed inverted, all was running well (there are no more artifacts too).
- Next, I tried with a series of RAW images and the buttons still had problems. Only after a couple of runnings they start to work correctly.
It seems that now all is working well. I must say that, with some images, the result seems better with the version 1.
