This is also visible in first person, and presumably to other players.
Unrelated, but the player model is very jittery when turning in first person on a horse.

I can look into that one. In regards to the dragon mod, I'm not 100% certain why it'd look like this in the third person. It looks like the mod might hide the real player and render a custom version of the player as part of the dragon model. Might take some time to look into it since currently some rewrites are being done. Is this with the current 2.0.0 builds?

It seems like this happens without your mod.. I'll open an issue in the Ice and Fire repo

This is on 2.0.0 Forge. It also shows in first person, with the players model duplicated in front of and below the camera

Can you confirm that it's the firstperson mod that causes the 2nd player to be rendered in 3rd person? I'm honestly not sure how that could happen since the "first person player" model only gets rendered while in first person by (in forge) tricking the game into thinking it's in 3rd person while you're actually in first person. Maybe the current fabric way of doing it changes this visual issue, or I might have to add specific fixes to not do anything while riding an entity of that mod.

Yea that's an odd issue. I guess it renders the 2nd player on the dragon and places the real player above to fake the 3rd person? Could probably be done better(at least hide the real player) 😅.
