TrackIR snaps to X/Y_Axis

[Hobbygeneral]

Hello,

I have recently bought a Trackir 5 and have a small but annoying problem. The tracking snaps for a split-second whenever it passes over the x or y-axis. Especially the y-axis when looking sideways out of the window and the up and down. It stops at the horizontal axis and releases after a short time.
I already checked and adjusted my TrackIR profile accordingly and removed possible deadzones.
And it really works well inside TrackIR with the virtual cockpit. Nice and smooth transitions in all directions without the stops in the middle. But in IL-2 Strumovik the problem is back. I doublechecked if the profile is loaded. All correct.

My best guess it has something to do with settings within Sturmovik. Camera-Settings? Snap-View? Do someone has a clue?
The view is set to Pan View btw.

Any reply would be greatly appreciated!
