[Octave-bug-tracker] [bug #41932] Solid line appears dashed with FLTK

[Michael Godfrey]

Follow-up Comment #9, bug #41932 (project octave):

Here is an observation on this long saga:
For a long time I have had to use:

set(0, "defaultaxeslinewidth", 1.0);
set(0, "defaultlinelinewidth", 1.0);

in order to get viewable plots. With widths
set to 0.5 not only were lines discontinuous,
but at some plot scales the axis and grid
lines would disappear altogether.

My system is x86_64 Intel with Intel graphics.
Fedora 20, now with most recent updates.

Over this period there have been many changes 
to most of the graphics-related software:
X11, OpenGL, antialiasing in Octave, and so on.

Yesterday many of the graphics libraries were
updated on Fedora, such as xorg and many libs like:
mesa-libGL-10.1-6.20140305.fc20.x86_64

So, I tried some plots with widths set to 0.5.
They all look good so far! The lines are thin,
but no discontinuities, or missing lines.

I am sure that we have not heard the last of these
problems, but it is pretty certain that the
recent problems are not all Octave's fault.

It may make sense to think of an explanation
for users that may avoid some complaints.

I will do some more experiments, including
checking the effects on print outputs.
