Constant jittering only on 2024. What changed?

I have been trying to figure out the cause of this jittering (ground and air) on 2024 over shared cockpit (yourcontrols) for nearly 4 months now. I have changed/tried 50 different things that could maybe cause this effect but nothing fixed the issue. This only happens on 2024 while everything works normally (smooth) on 2020. Trying the 2024 SimConnect.dll and exporting WASM with 2024 SDK was the most obvious fix but it did not fix.

I would appreciate it if Asobo could at least point me in a direction to look.

interpolation with the aircraft is perfectly fine while the world appears to shake based on speed. Some have also suggested it’s worse with higher FPS. I have tested with ONLY syncing longitude/latitude and it still jitters. Observer POV (over LAN connection) video below:
