Weird edge rendering

[lafrank]

Sometimes, after redrawing graph edges, they are rendered in a weird way:

When moving nodes and the graph is re-rendered, edges are drawn as expected normally :

What parameter in below graph layout algorithm makes it happen this way, what to change to avoid the first rendering mode ?

Thank you in advance.

The parameters look okay. I think what happens here is that an exception is thrown during the edge routing and the routing does not finish. That is why the edges don't look regular.

Thank you, let me check it.
