I am not an advanced DX user therefore I know nothing about the scripting possibilities you are using. In the networks I build in the visual program editor I use the 'image' module to produce the graphics. Doing so an 'image' window opens when the program is run. If I choose 'Options --> Rendering Options...' in the menu I can choose between software and hardware rendering. I encountered strange black lines comparable to yours before when I switched from one to the other and reexecuted the visualization network.
Would be interesting to know if this resolves your problem! And it would perhaps explain why other people with other graphics hardware do not see this black line.
