Same problem here with fltk and Debian 7.0. Broken/missing  lines
already present in current released version.
I have an Ivy Bridge if that is of any help.

I have spent a little time on this and it appears that this is a fairly major
screw-up in Fedora 18.  It appears to involve  OpenGL, the graphics drivers
(not just nouveau, nvidia, and Intel) and selinux (due to wrong attribute settings)
and surely more than a few other things.  It will likely be some time before this gets
straightened out.  It is hard to see how we (Octave) can deal with this.

It may be best to flag this as a current problem with FC18 and other recent
Linux releases.  Sadly, the obvious work-around is to go back to gnuplot.
(However, I recently noticed that gnuplot is also affected.  The plots in the
Manual are not all quite right if built on Fedora 18.)
