No response from OP for several years, the original example posted here is faulty, so hasn't been reproducible. If this bug is still valid, more information can be provided or a new bug report filed.

I can't get the code sample to work.  When I try just the fill command by itself I get

h=fill([90,210,210,90],[-.8,-.8,.8,.8])
h = -1.5020
error: __go_draw_axes__: A(I): index out of bounds; value 1 out of bound 0
error: called from:
error:   /usr/local/share/octave/3.6.4/m/plot/private/__go_draw_axes__.m at line 735, column 30
error:   /usr/local/share/octave/3.6.4/m/plot/private/__go_draw_figure__.m at line 167, column 19
error:   /usr/local/share/octave/3.6.4/m/plot/__gnuplot_drawnow__.m at line 86, column 5

This occurs with either backend.

The EdgeAlpha and/or EdgeLighting properties do not seem to have an effect on Fill() or patch() plot objects.  Example code:

f1=figure(1)
clf;
hold on
grid on
h=fill([90,210,210,90],[-.8,-.8,.8,.8]);
set(h,'FaceColor',[0,0,0]);
set(h,'FaceAlpha',0.25);
set(h,'EdgeColor','none');
set(h,'EdgeAlpha',0);
set(h,'EdgeLighting','none');
axis([50,250]);

What I expect is a totally flat, featureless transparent rectangle.

What I get is a transparant rectangle but nothing I try gets rid of the edge of the rectangle.   I have tried various values for EdgeAlpha without success.  Same for EdgeLighting.
