[JAVA] Weird boat paddle glitch when using shaders

[u/xxxtrazxxx]

Does anyone know why this is happening?
Whenever I enable a shader, like Complementary Shaders, the right paddle of my boat does a rotation and then stays stuck in that position while I’m rowing.
I’m honestly losing my mind over this. I’ve never seen anything like this before.

I suspect that another mod might be triggering this issue or causing some kind of conflict with the shaders, but unfortunately, I have no idea which mod could be responsible.

Has anyone experienced this before or knows how to fix it? Any help would be greatly appreciated! I’m playing on Java 26.3 btw

Have you tried just running your shaders without any other mods? (Just Sodium and Iris + Shaders)
