There are well-known rendering issues with mplot3d in general, but I am not
aware of one with respect to bar3d.  Can you please include a image of the
rendering defect that you are seeing?

And no, there is no way to disable z-sorting that I am aware of because it
is inherent in matplotlib's system.  mplot3d merely utilizes the drawing
facilities that matplotlib provides.
