Ulli,
Oh, thanks for motivating me to find the Edit->Information panel. I was looking for something like Options or Preferences, and had missed Information. I wonder if changing the name to Options might help others get oriented?
In any case, turning Antialiasing on and off doesn't change anything in my animation, although my animation doesn't have any labels.
What does make a difference is double buffering. If I turn double buffering off, then the animation works fine. If I leave double buffering on (the way the software ships) then the animation is jerky and flickering. So turning double buffering off completely solves the problem. Maybe the software should ship with it turned off by default?
When double buffering is turned on, one of the things that happens in the animation is that the animation control tools keep getting written over by the grey background, so that they flicker horribly. I think the same thing is happening with the geometry elements, and that this is what causes the flickering, erratic animation. Turning off double buffering stops this from happening.
Now, this description of what happens seems exactly backwards from the way I would expect it to work. Shouldn't double buffering make the animations smoother? Could it be that double buffering is actually on when the Information panel says it is off, and off when the panel says it is on?
