Just to add one last note in case anyone is interested. I was
using okular to view the PDF.Switching to evince had the effect
that the blue lines were more visible.

I looked at this a bit more and discovered what is happening:
The problem is with the rendering of the PDF. My plot is
actually 6 subplots (2x3). If I zoom in enough the color shows
up. The color that I was using was blue, which did not help
make it more obvious.

So, time to close this report. Sorry for the bother.

I was hoping that a simple example might show the problem.
The case that fails for me is within a set of scripts that
generate a series of plots for a paper. I will try to extract
a simple example, but this may not to possible right away.

I just notice that the current gl2ps on Fedora 25 (with latest
updates) is gl2ps.x86_64 1.3.9-2.fc24. Is may not be
the "latest."

Hi,

Can you please provide code to reproduce the bug. I tried this

and obtain the attached pdf with both lines visible. I am using the latest default tip (and the latest version of gl2ps in case this may be relevant).

HG ID for this build is "7c7a61c2e0ed"
In this build a plot which has a line drawn coincident (on top of)
a grid line appears on the screen. However, the line does not
appear in the PDF output.
Using version 4.0.3 (Fedora release) the line does not appear either on screen nor PDF.
