              Marking as resolved. 6.0.1 introduced tile scaling which appears to fix the issue as the document is zoomed.

              The file associated with 13196 is similar but image based in nature. The diagram is made up of many small image tiles and the thin lines on these images aren't being painted unless the zoom level is increased.

              I've tried tweaking the Java2D system properties but haven't had much luck getting the lines to draw. The line is very thin and Java2D is not painting it a low zoom values. If the content is zoomed in the lines are eventually painted.

              The line thinkness can be adjusted as part of the specification is specified by the stroke in the content stream. We might be able to tweak the line thickness is indeed a very thin line. I'll need to look into the content stream to see if I can isolate the postscript that describes and draws the line.
