Using interpolated image_maps in functions results in pixel-sized dot-artifacts when using the functions back into pigments.
This problem doesn’t shows using the same code on POV-Ray 3.6.
I qualified it as “low severity” because is not going to happen to most users: it will show only when using some advances techniques, for example when you want to decompose an image_map into the RGB components, perform operations, and mixing them back with an averaged pigment (example attached).

Reason for closing: Fixed
Additional comments about closing: no news, so I guess the fix was effective
