This must be a bug of some sort.
The images show a screen shot of an OpenGL 3D view, compared with the same view after saving it with a "save as" command. Saving or printing degrades the image, both in the saved file or print and on the screen as well. The degraded image is showing elements that should be hidden by walls in front of them.
Rebuilding the image from the model fixes it.
The screen shot is the only way I have found to save a good image.
Results are the same, regardless of the format chosen for the save. Printing also gives the same problems.
