As it wasn't on-topic on the other thread about the TGP slew and HAD, I'll create a thread of my own instead.
After the latest patch I've noticed that the TGP sometimes can't stay stationary on one coordinate (i.e even the coordinates in the top left corner of the TGP are slowly changing). I have double-checked that my slew controls are perfectly centered, and even so, I can observe this while the TGP is locked in point-track.
From my observations this "drift" always happens in the same direction as the aircraft is moving, so if I am moving straight against the target, the TGP will drift further away on the ground, and if I am traveling towards the left in relation to where my TGP is pointing, the TGP will drift in the same direction.
I have even tried saving markpoints with the TGP, flown around a bit and then cycled through the markpoints and making sure I'm doing Cursor Zero on the TGP, and I can observe that the TGP suddenly points way off the markpoints that I had placed.
I have noticed this complaint from other players on multiplayer servers, so I'm not the only one experiencing this.
Attaching a track-file to this post demonstrating this.
