Rhino7: Unable to correct messy textures

Yes, all images are in rendered mode. I’ve got the Rhino5 version of equ.073:

equ.073.PneuBulkheadPlt2_200.3dm (2.1 MB)

On my machine in Rhino5 it looks correct.

I meanwhile did a system recovery back to the point before I installed the latest AMD driver (January 3rd) because I felt some of the texture problems occurred since then - and yes, obviously the latest AMD driver has problems with Rhino7:

Latest AMD driver:


AMD driver 2017

This however does not cure the initial problem of erratic and messy textures mentioned above.
I gladly can upload parts of the project, but please be aware these are hundreds of files, the oldest stemming from 2010 and Rhino3/4 and now mixed versions of Rhino5/7.

thanks
