Surf plot mesh looks jagged when I set FaceAlpha

Below is the example given in the "surf" documentation. The mesh looks smooth when `FaceAlpha` is not included but it looks jagged when it's transparent. Is this a graphics card issue or can it somehow be fixed?
[X,Y] = meshgrid(-5:.5:5);
Z = Y.*sin(X) - X.*cos(Y);
s = surf(X,Y,Z,'FaceAlpha',0.5)

Let me think... You are using r2013b or r2014a or so? If so then there was bug having to do with opengl use, which gets enabled automatically when alpha is used.

It looks nice in my Matlab 2016b/Win10. Setting the Alpha blending enables the OpenGL renderer. If this causes troubles, try:
opengl software
Does this help? Do you have the current versions of the drivers installed? Which OS are you using? Can you post a screenshot such that "looks jagged" gets more clear?
