Both the orbit line and the ship look really weird. Something's wrong with the grid too, but you can't tell without artificially slowing down the time, as it's going so fast when the camera is that close.
I don't really know the reason, but I am assuming it has something to do floating point rounding errors. I'm also pretty sure that there are multiple effects going on here, as artificially slowing down the time in the integration code at least stabilizes the ship.
