I've filed a bug report for 2)

        https://savannah.gnu.org/bugs/index.php?35307

I'm unable to help with 1) or 3) as I can't duplicate the problem.

If you can give us more details as to how the figures were produced (from the 
command line, in a script, in a loop, in rapid succession, etc) we maybe able 
to help isolate the conditions that produced the incorrect result. Also for 3) 
was the problem with fltk, gnuplot, or both ?
