Thin lines on graph are not rendered.

Summary: The uploaded PDF "pdfwithproblem" doesn't render correctly when converted to an image. Only part of the line graph shows on the Poppler image. I am able to reproduce this in Adobe Acrobat X Pro but not able to reproduce it in other PDF readers (Chrome, Acrobat Reader). I can fix the issue in Adobe Acrobat X Pro by unticking "Smooth Line Art" using "Adobe Acrobat X > Edit > Preferences > Rendering > Un-tick > Smooth Line Art fixes" but of course this doesn't fix the Poppler image rendition. The issue is also in XPDF.
pdftoppm version 0.51.0
- Run "pdfwithproblem" through pdftoppm to create an image.
- "pdftoppm-withlcms -cropbox -f 1 -l 1 -r 202 -png rendition.pdf pageImage"
Expected: Lines on graph render correctly. Please see EXPECTED_pdfwithproblem
Actual Lines on graph not rendered. Please see ACTUAL_pdfwithproblem.
