            Description

            Not sure how I haven't seen this before but the line in question that isn't being displayed has a hard line thickness of 0 which is well invisible. There is a note in the PDF spec that states:
            A line width of 0 shall denote the thinnest line that can be rendered at device resolution: 1 device pixel wide.

            We can pretty easily compensate for the given CTM scale and specify a none zero stroke that should show up at most zoom levels.

              Marking as fixed. Added some compensation code for zero width lines, as the spec says we should be painting something regardless.
