I just checked it out.
It looks like you have your elevation set to show 'Surface Colour - Shaded' - which means it is applying shadow to the surfaces - exaggerating the facets.
Try setting it for 'Surface Colour - Non-Shaded'.
You will have the same problem in 24 and before.
25 also has a new 'Surface Texture' option, but you probably won't want that.
It will show the actual texture image, but it doesn't wrap it around the curve.
