As the title states, the orbital paths of objects farther than Mars seem to shift away from the planets' actual positions as seen in the attached images.

it seems to be an issue regarding the amount of lines that make up the path, as seen with Sedna where it will drift in and out of alignment
Yes this is simply due to the enormously large orbits at further and further distances from the sun and that the points for the orbit lines are finite. We could certainly add more and more points, but this reduces performance. There is a plan to revisit how the orbit lines are drawn at a later date.
