Rear Image in Open GL before SP3

I found VW9 through SP2 was rendering those crazy lines in custom OpenGL show edges option enabled; was hopeful about SP3 fixing that and in one file it did and others(?) still have those messy lines. It was brilliant to do fly-overs around a model with no textures nor colors (as we all know OpenGL will not show this well otherwise) and get all the correct lines with show edges option enabled but this does not seem to be consistent and therefore an option I can't use either.

Please fix this.

I personally don't view OpenGL as any more than a quick and interactive preview. Its capabilities, performance, accuracy and quality are too much in the hands of the graphics card manufacturer. The OpenGL renderer is implemented by the graphics card manufacturer and not the application as with other Vectorworks render modes. A render can give different results depending on the graphics card.

It is possible that these issues may have nothing to do with Vectorworks and are simply artefacts of the particular OpenGL renderer built into the graphics card.

One additional fact ... Apple has a habit of coding Quartz into the cards to make them OSX specific. The issue could very well be related to the implementation of Quartz.
