MATLAB: MATLAB movie2avi cannot made video

moviemovie2avivideo

I am trying to test the function movie2avi using simple codes in R2014a as follows:
    clear; close all;
    figure;
    Z = peaks;
    surf(Z);
    axis tight manual;
    ax = gca;
    ax.NextPlot = 'replaceChildren';
    loops = 40;
    F(loops) = struct('cdata',[],'colormap',[]);
    for j = 1:loops
        X = sin(j*pi/10)*Z;
        surf(X,Z);
        drawnow;
        F(j) = getframe(gcf);
    end
    movie(F);
    movie2avi(F, 'myPeaks.avi', 'compression', 'None');
It seems the movie(F) works well but the avi file created contains the toolbar and background instead of just showing the graph. Also the avi file just show stationary picture as follow:

Another version of the program produce the same result: clc;clear; close all;
figure;
Z = peaks;
surf(Z);
axis tight manual;
ax = gca;
ax.NextPlot = 'replaceChildren';
v = VideoWriter('newfile2.avi','Uncompressed AVI');
open(v);
loops = 40;
F(loops) = struct('cdata',[],'colormap',[]);
for j = 1:loops
    X = sin(j*pi/10)*Z;
    surf(X,Z);
    drawnow;
    F = getframe(gcf);
    writeVideo(v,F);
end
close(v);
There is also a warning:
Warning: Struct field assignment overwrites a value with class "double". See MATLAB R14SP2 Release Notes, Assigning Nonstructure Variables As Structures Displays Warning, for details.
Please help. Thanks.

I added a command "set(gcf,'Renderer','zbuffer');" when I use R2014a and the problem is solved. It is just like using writeVideo in R2015a without that command. Thank you.
