Orbits fuzzy on docking levels

I have so far only encountered this problem on the Docking Practice level and the Satellite Rendezvous level. The orbits get pixelated and start vibrating. Additionally, the sizing of the blue ship icon gets a bit off, although this is less noticeable. It seems to occur when there is more than one craft at the start of the level and when there is an uncompleted objective. It does not happen with stage separation in other levels, nor does it happen in sandbox mode. The problem also disappears when the objective is completed (see final image). I have tried both levels multiple times and restarted Steam, so I don’t think this is just a one time thing.
