Can not add box and ticks to a colorbar

Hi guys, I can not add box and ticks to my colorbar. My code is

surf(xx,yy,zz)

cb = colorbar;
cb.Ticks = [13 15 17 19];
cb.TickDirection = 'out';
cb.TickLabelInterpreter = 'latex';
cb.Box = 'on';
cb.Position = [0.88 0.15 0.03 0.7];
cb.FontSize = 8;

Then I got this figure

I have tried to make the box on the changed the ticks length, but nothing happened.

If I use export_fig to output pdf files. I got:

 You seem to be using axes that have overlapping/hidden graphic elements.
Setting axes.SortMethod='ChildOrder' may solve potential problems in EPS/PDF export.

But I don't understand the meaning.

The output pdf file has ticks and the box as shown:

Any idea?

Thanks!

I can't reproduce this on R2020a or R2018a. I didn't install R2019b to confirm, but I'm assuming this isn't with a fresh figure with the default axes creation functions.

You might consider using explicit handles to your figure and your axes object.

I use

f.Position = [4 4 3 2.4];
ax.Position = [0.55 0.4 1.9 1.8];    

to define my axes and the figure. I am not sure if this will affect the figure.

I have r2019b but you'll need to provide a complete example that I can copy-paste (and perhaps load variables) so I can run it. Make sure the example produces the problem on your end.

Also, check that you're using the most up-do-date version of export_fig. The author has recently made updates.

This problem is from my AMD graphic driver.
