Patchy Polygon

Hello,

I'm having trouble with polygon fill appearing patchy when rendered either with a color or image and aligned (align shape to terrain) to a terrain that has an image draped on it.  It appears as though part of the image is falling under the surface .  (see attached)  I tried aligning the terrain to shape with only a slight improvement. 

Items of note:
1. the terrain and the image are the same extent.
2. portions of the outside boundary of the terrain are 0 value.  it was derived from contours that were clipped.  The range of the height values is from 0 to 679 with all the non-zero values falling between 579 and 679. 
3. none of the features on this polygon layer fall outside of the area of non-zero value terrain

Has anyone had similar issues?  I'm actually looking to bring in many more polygon layers to cover a good portion of the terrain.

Thanks,
Jim
