surface command is conecting the end points of a surface

I can't figure out why surface is connecting the end points of the surface. I have attached an image so you can see what I mean. let me know if more information is needed I am specifying surf(x,y,z,'edgecolor','none').

The image did not get included.

Hi,

Please share the data that was used to generate the surface plot.

Also, the version of MATLAB and the graphics card. You can get those with:

ver
opengl info

The old OpenGL renderer would encounter a bug that sounded a lot like that on a particular graphics card, but I'm afraid I've forgotten the details on that one. The newer OpenGL renderer that was introduced in R2014b doesn't hit that bug. So if you're on a newer version, it's not that one.
