It may not be very clear, but if you look in the images you might notice a certain zig-zag triangular artifact. It seems to only occur on 3D object primitives (ie, not planes and circles) when the object is somewhat transparent.

I'm sure this is a OpenGL rendering issue and not specifically a Jitter problem, but I'm not sure if 

1 - can this type of rendering be changed or improved somehow?

2 - what options are available in Jitter to do so? Is this a jit.gl.render config issue?

Any thoughts, helps, suggestions would be appreciated.

it looks to me as though you have @blend_enable 1, @depth_enable 1? try turning off depth enabling.

first of all I'd like to say I'm glad I'm not the only one that was 

I have wondered this before and got the general impression from the 

response that "that's the way the object works".

There is a simple explanation, however - try the patch below for further

Hi Greg,
first of all I'd like to say I'm glad I'm not the only one that was 
stumped by this!
I have wondered this before and got the general impression from the 
response that "that's the way the object works".
There is a simple explanation, however - try the patch below for further 
confusion.

I tried switching these on the jit.gl.render object ... no change.

I'm mainly using jit.gl.mesh to create the shapes ... I have also tried disabling depth_enable .. no change.

If I disable blend_enable, I can't achieve any transparency - so I can't really reproduce the effect.
