Kerbal Space Program

Just noticed that placing a maneuver node sometimes stops the flickering

this is normal for a circular orbit.

What is happening is the simple act of firing RCS to change your orientation is altering your orbit. The closer your orbit gets to a perfect circular orbit, the more jumpy the nav points get.

The only "bug" here is the fact that you can change your orientation with RCS turned off. This is a physics shortcut, and it does cause bouncing nodes even though they aren't actually changing at all. The game doesn't actually change the orbit for this free rotation, so the bouncing is a visual nuisance that maybe should be fixed for a final version, assuming that free rotation isn't simply removed entirely to increase realism.

This problem also ocurres on Linux with Ascending Nodes, descending nodes, planet intercepts, peripexes, and apopexes under various circumstances.

They flicker and twitch in various patterns. It is usually caused by close matching of the values being compared to create these points. However, I have not figured out what causes the planetary intercept points to flicker, but those tend to stop doing that once I move closer to them.

The flicker and twitching does not occur during time warp. This is likely because it is not recalculating the path during these times.
