arsbor,
Actually, in your case, I think the issue was also caused by the bad array
construction and plot_surface() was getting bad data depending on the
strides. There is no random number generator in the code-path, so
*something* must change. I noticed that it would happen as I changed the
cstride/rstride values for the top cover (before I had fixed the top
cover). If you still notice the issue now, let me know and I will look into
it further, but it shouldn't be happening for you.
