Has anyone seen such scanning artefacts before?

Hello everyone

I'm having trouble with my new-to-me X1 which produces weird smearing artefacts below certain resolution levels, 2000dpi for 135 film and 1000dpi for 120 film. Here are a few examples:

The error only appears if I scan as TIFF, not 3F, and seems to be concentrated to high-contrast areas and areas of fur, hair and such with lots of details. The error is not local to a particular part of a frame but can appear anywhere in the frame. It is visible in both transparency and colour negative film.

Weirdly, the error is still there after the scanner has been serviced by a former Hasselblad technician in Germany.

I run the current version of Flexcolor and a fully updated El Capitan but the error appears if I scan on a completely fresh install of OS X El Capitan which only has Flexcolor installed. Also, the error appears regardless of which Firewire port I use on my Mac Pro.

Has anyone seen anything like this?

Thanks a lot in advance for any thoughts.
