That's a known issue. It also happens when saving out wireframes. The problem is that we use glPolygonMode to render a surface as wireframe. That produces closed polygons at window borders. When saving a large screenshot, we use tiling to render an image larger than the window size that introduces artifical window borders and hence those extraneous lines.
Any OpenGL experts have any idea how to overcome this issue?
