Try using a higher Antialias_Depth value. I have a similar problem when using
planes with checker textures. Near the horizon I get some jitter but it doesn't
change through different frames (unless I change camera angle).

Using a higher depth, I get less jitter, but you can't get completely rid of it.

You can also try using sampling method 2 (slower) or blurring the final image(s)
a bit with a picture modifying program.
