Are those general 3D OpenGL views? It looks like it tries to generate some kind of transparency/Antialiasing thing, and it fails.
Please see what happens if you save it to PDF (or if you saved it to PDF before, then try printing to PDF).
Does the same happen if you do it on a different computer?
Also, as a solution for the meantime, you can try using 3D documents instead of 3D views. They are vectorial so they should not be prone to such errors.
