Ok, perhaps some miscommunication on this issue, but here's one way to
reproduce it.
If you can setup two flightgear machines and use the --native-fdm= protocol
to drive one of the machines from the other, you will see the bug on the
receiving machine that is being driven by the sending machine. This is
where I see the problem. But I'm certain that the same issue exists when
you control flightgear from any remote source (either replaying a saved
flight from a file or driving flightgear from live flight data, or driving
flightgear from another copy of flightgear.) Notice that this issue has
nothing to do with FlightGear's built in record/replay system that can
replay your last few minutes of flight.
If you don't have the hardware to setup two PC's simultaneously, I could
walk you through some other ways to reproduce this.
Let me point out that in the past, the chase views computed their positions
as a direct offset from the aircraft. So the chase view position was always
exactly some distance and direction from the aircraft and directed at the
aircraft. With the new nasal code there seems to be a timing element that
is introduced so the relative view position jumps forward and backwards
every frame compared to the aircraft, this makes the aircraft (and possibly
the scenery if you are close to it) appear to jump backwards and forwards
every frame. Oh, and this issue only seems to be a problem with the chase
views. The cockpit views and the fly-by view seems to be ok.
Thanks for taking a look at this,
Curt.
