[Octave-bug-tracker] [bug #51444] surf(): additional white lines in surface plot

[Hartmut]

Follow-up Comment #2, bug #51444 (project octave):

I have compiled the current dev version of Octave (hg id b85a46745298 of
today) on my Linux system:

* I can confirm Dmitri's observation that the demo code in comment #0 does NOT
have those white lines any more. 
* BUT when I use my mouse to rotate this 3d plot, then I DO see those white
lines come back, quite often.

A demo script to reproduce those white lines in current dev Octave is this
(just a changed view command):


clear, close all;
graphics_toolkit qt % fltk is the same, gnuplot is fine

x = [-3:1:3];
y = x;
[xx, yy] = meshgrid(x,y);
zz = xx .* yy;
zz(zz < 0) = 0;

surf(xx, yy, zz, 'EdgeColor', 'none');
view(30,85);
grid off;


I will attach a screenshot of this tilted 3d plot with current dev Octave
(under Linux).
