Off hand, it looks to me like the normals are wrong. The bright white vertices usually result from a normal being far too large. AC3D has been known to generate some very strange geometry in the past, and it's possible that it is confusing plib's normal calculation. Try to look through the file and verify that you don't have any degenerate triangles, etc...
Or, if you are feeling adventurous, try my plib patch which replaces the normal calculation step with a smarter one that understands the difference between smooth and sharp edges:
http://www.plausible.org/vertsplit/vertsplit2.tar.gz
(Make sure you are using the CVS version of plib, dump all the files in the tarball into src/ssg, then rebuild plib and FlightGear).
The two implementations share no code, so if the problem persists with the patch, the bug is almost certainly in your model file.

This is a known issue that gets reported from time to time. The 2D panels use a depth buffer offset to draw the layers, and it ends up being too coarse on 16 bit depth buffers. Try setting your screen depth to 24bpp and see if that fixes the issue.

Are you sure you didn't change your display settings and/or take the screenshots on a different machines?
