[Paraview] Possible Bug: cross drawn over upsampled screenshot

[Olumide]

Hello,

I may have discovered a bug in Paraview's (version 3.6.1) save 
screenshot feature. It seems to affect only wireframe representations. 
Would someone please try to reproduce it. Here's how to do so:

1. Load any geometric object into Paraview, or create a geometric 
primitive e.g. from the sources menu

2. Change the representation of the object to wireframe

3. Open the save screenshot dialog (File -> Save screenshot), and 
increase the default width or height of the output image by at least one 
pixel.

4. Complete the export and examine the output image. A cross is drawn 
across the output image as shown in the url/image:

This artifact only observed when the default dimensions are increased. A 
  reduction in the default dimensions generates no such artifact.

Thanks,
