I looks as if you are right, it is a rendering problem. One strange thing is that when I start DX in interactive mode, I do not see the diagonal line (but the color of the square is white). Then when I open the "Rendering Options" window, choose "Software Rendering" (i.e. do nothing because it is the default) and "Execute Once" to redisplay, the diagonal line is there. Switching to hardware rendering gives the picture without diagonal (and the color is changed to blue). But I do not know how I can force hardware rendering from within dx/script (I have tried several things which did not work). Maybe this indicates that some libraries for hardware rendering are not found by dx/script? Hmm, maybe I should face now the task of interfacing my PDE solver to the GUI-DX via DXlink... I'll ask some questions in a separate message. Thank you, Nicolas.
