[Paraview] holes in distributed polydata

I'm seeing lines where the background shows through a surface polydata 
of quads. When I zoom into the region to investigate the holes are gone. 
Moving the image around the holes appear in different places. They 
depend on camera position. In this surface there are 2.5E6 quads. the 
area is 10x16 units and the number of quads is 1250x2000. each quad has 
0.008 units on a side. I hadn't seen the holes before going to this 
higher resolution. It's likely that the hole is near a process boundary, 
in my polydata filter each process adds his quads to his output 
polydata, in this run the quads are distributed in strips of 512 as needed.

3 holes/lines in bottom half of the image (black background shows through):

zoom in no holes/lines:

process boundaries (from process id filter):

Should PV be able to handle a polydata distributed like this?
