Coincident face Z-fighting remains an issue. This was a problem before this face displacement work and was not specifically addressed. Larger displacement settings may alleviate such issues.
Highlighting can also be affected by the face displacement change since it relies on displacement.
Bounding Box:
If the bounding box of the entire model is inordinately larger than the specific model being viewed, this can have an adverse effect on the rendering (such as, more pronounced z-fighting, edges bleeding through faces). The PartViewer can be used to show the bounding box (Tools -> Segment Browser -> Boundings):
...
If the bounding box is inordinately larger, try simplifying the scene by removing geometry or by extricating the smaller target model in question on to its own separate file.
Camera Near Limit:
Adjusting the camera near limit closer can help as well, as this results in better usage of the depth buffer.Highlighting can also be affected by the face displacement change since it relies on displacement
Changing the near plane of the camera can sometimes fix displacement rendering artifacts. As stated in our HOOPS Visualize docs under the heading “Changing the Camera Near Plane”:

…by default, Visualize will automatically adjust the near clipping plane to be as close to the camera target as possible but this may not yield the best rendering results. Try changing the camera near plane by small incremental amounts both in the positive and negative direction, for example, +/-0.01 or even by +/0.001.
