It looks like the issue with using the same group for all series - which is fine in 2D, but cause rendering issues in 3D. Connected ticket: #4369

Hi guys, is there a solution to this issue yet?

As a workaround you should be able to modify SVGRenderer.prototype.cuboidPath and inside this method change an idea of calculating zIndex for columns. http://jsfiddle.net/4y3qgdmn/32/

In this case it is necessary to change where series is rendered. Instead of individual groups per series use just one group for all series’ points.
