The airplane symbol in the given example sometimes "jumps/flickers". It seems that in some occasions there is a problem with calculating the orientation of objects moving along the path.

Agreed.

I wonder if anyone had been able to look at this bug?
Comment 3 Dirk Schulze 2011-05-26 23:58:06 PDT
Rob and me realized that it even got worse. The plane is not visible at all in trunk.

The example link no longer works. Should the status be updated to WONTFIX?
