OpenGL Issue with multiple transparent textures

Question

Here's an issue I've seen pop up in Vectorworks for years, and I'm curious if anyone knows why it happens or a possible solution.

 

If you have multiple objects using textures that have an Image Mask for transparency, sometimes OpenGL will display the obscured surface in front of the foreground surface. Take a look at this video:

 

 

I've also seen it happen to surfaces of a single object using just one transparent texture (such as the back side of a cylinder being displayed in front of the front side, which is really trippy).

 

Seems to be related to the angle of view somehow.

 

This makes using the Walkthrough tool to present to a director or producer very difficult because it makes the software look cheap and buggy.

 

(BTW - in this example I know I can just model the black grate as actual geometry to get around this issue, but I'm interested to know if there's a way to address the actual issue so that overlapping transparent textures don't have this bug.)
