This is fixed in Roassal1.456. There was indeed a bug in the code.
Now, there is the following:
- A node is rendered if its bounds intersect with the bounds of the camera
- An edge is rendered if at least one of its extremity has its bounds intersect with the camera
As a consequence, an edge that has no extremity on screen is not displayed. Even if the line "go through" the camera bounds. Naturally, this is something that is easy to change. We can provide particular strategy to define what makes an edge visible or not.
Cheers
