Hi,

This is a duplicate of bug #45494, which I just retitled to ease the search. Anti-aliasing is now disabled for raster outputs, so only vector formats are affected.

Closing this report as a duplicate.

I can confirm this problem.
Accidentally I noticed that pdfs distributed with -rc2 tarball are produced by gnuplot.

This is the PDF form of the manual, right?

I see the pale diagonal lines you describe in hist.pdf only, and only when built with OpenGL and OSMesa. The following command specifically, for me on my system (Intel integrated graphics), reproduces this problem:

If I unset DISPLAY, which forces gnuplot to be used instead, then I get the correct image without the pale diagonal lines.

The files hist.eps and hist.png do not exhibit this same artifact, at least for me.

Attached hist.pdf here, in case others are not able to reproduce.

I remember that the problem now shown was once fixed, but
I cannot locate a reference. The problem that has returned
is that the histogram plot (Fig. 15.2) in the Manual shows
diagonal dashed lines within each histogram box.

The command in Octave: hist (randn (10000, 1), 30);
shows a correct histogram. Only the Manual is incorrect.
