Must be something to do with software rather than ice crystals between the sensor glass. Bit of a loss to explain this.

… the Bin settings turn out to be a red herring! In summary:
*The artefacts appear once the camera cools below Zero Deg C
* The artefacts always appear in the same position.
* They disappear once the camera has been powered on for 5 to 10 minutes.
