[Octave-bug-tracker] [bug #41608] Default FLTK linewidth is too low for some video cards

[Mike Miller]

Follow-up Comment #15, bug #41608 (project octave):

I'm good with backporting the patch to stable. I built 3.8.1-rc3 with the
patch locally applied and it works for me. It is currently applied on the
gui-release branch for the 4.0 release.

I'm also good with keeping the default line and axis width at 0.5 for
compatibility.

However, it is still an issue that the 0.5 line and axis width appears
significantly different on certain video cards (I can attach screen grabs if
that would help explain the difference), and that's what this bug is currently
about. Maybe it's something specific to FLTK's use of OpenGL, or maybe it's
something specific to OpenGL support on certain video cards, and maybe there's
nothing that can be done about it in Octave, but that's where we are with this
bug report. Applying the patch doesn't simply make 0.5 OK for everyone.
