Cubic Subdivision still broken with new 2.4 beta release

[rexipus 0]

The Cubic Subdivision feature, one of the marquee features of the 2.4 Beta, still doesn't work on my machine. Others chimed in saying they saw this too. I uninstalled the original 2.4 Beta version and installed the new version that came up a week ago.

On my machine all that shows up of the infill, when set to Cubic Subdivision, regardless of the percentage, is a single line in the upper left arm of this quadcopter body.

My machine is an Intel i7 6900 with 32gb of RAM running Windows 10 64-bit, anniversary addition with all the latest Microsoft updates. Video card is NVidia 1080 with most recent drivers.
