Animation/rendering bug?

I have noticed that my avatar is shaking, and not from laughter, I'm afraid.

I am standing still (supposedly) and I am looking at another av. My head shakes violently. Or my legs have shimmies. (The object of my gaze is neither so beautiful nor so hideous as to make that condition an obvious reaction.)

I've been told that this is a recent artifact that occurs most often at higher altitudes. (My land is high, and I have a treehouse on it.)

If I move away from the other av, it usually goes away. Does anyone have any *helpful* suggestions?

Is this question about creating your animations or just behavior? If it is the latter, the avatar intends to look where your cursor is placed on the screen. Try to move cursor or enter mouselook once.

It is behavior. Yes, I can look elsewhere or I can move back a bit and that will fix the problem. But why are my legs shaking? It is as though the system can't decide which of two positions it wants that body part in, so it alternates between them. Very very fast.

Are you standing on the plane ground? Sometimes legs move on the uneven place.

Nope. I've now seen the behavior at low elevations, too. (I guess I spend too much time with my head in the clouds.)

It is hard to explain unless you know about keyframes. It happens when you don't have higher priority than 2 on your legs and the location is uneven or the height is changing. The bad overriding happens. It might be a bug. Not overriding, but wrong direction leg.
But you should know that it happens depending on the location. Easy solution is just leaving there. If you want more, take the snapshot and send bug report. It is repeatable.
It has happend since I came here first, ver 1.5.
