Problem with white lines showing up when exporting surf plots

How can I get rid of white lines that appear when you export a surf plot as eps or pdf?

I've already checked out the following answer which appears to be 4 years old and does not work! https://se.mathworks.com/matlabcentral/answers/290313-why-is-vector-graphics-chopped-into-pieces

Here is an example of the artifact that shows up when you export a surf plot!

z = peaks();
figure
surf(z,'EdgeColor','none','FaceColor','interp')
print(gcf,'-depsc','-painters','out.eps');

There are white lines showing up in the figure!

Here is a zoom on a particular section of the figure above where you can see the horrendous export Matlab performs.

How do I fix this?

I suggest you call tech support. The developers are aware of the "white lines issue" and have been trying to fix it but evidently it's really tricky. They've solved it partially but not 100% yet.
