Details:

If I plot and print a 3D graph with mesh, surf (...) the y-axis and grids
behave unexpected. The Y-axis is thinner than any other axis or grid. Setting
a linewidth lets it scale with the other lines, but it stays thinner. The
grids in the background show a random behavior. 

Plotting the same data with plot3 though produces axis and grids just as
expected. The Code below demonstrates this. 

[X,Y] = meshgrid(-8:.5:8); 
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
plot3(X,Y,Z)
grid on
set(gca(), "gridcolor", [0 0 0])
set(gca(), "gridlinestyle", "--")
print('-dtex',"-S200,150",'plot3');

mesh(X,Y,Z)
grid on
set(gca(), "gridcolor", [0 0 0])
set(gca(), "gridlinestyle", "--")
print('-dtex',"-S200,150",'mesh');
