--- Comment #24 from caulier.gil...@gmail.com --- Maik, Look like with one or more than one core, the result is the same. Mathieu, Did you use the Color Management option ? If yes, can you try again with CM disabled and just one core ? Perhaps something goes wrong with one of your ICC color profile when preview is extracted in maintenance tool.
