Hi @Jade_NL , thanks for your answer, yes i am on windows.
what i did: first i tried to reproduce this on a different computer with the same dev-Version and found this blue eye again. then following your advice, i downloaded the newest build, loaded the happy little dog and applied the existing pp3: blue eye again in a little different shape.
Then i applied the pp3 to the playRaw Dublin Bay Rose, up close. and found the blue circle again:
Both are NEF-files, but i cannot reproduce on other NEF-files.
Now, since i cannot reproduce on other pics, i dont have any idea, how to create an issue on github…
