When using the Iris Shaders mod (version 1.8.12+1.21.1-neoforge), I encounter a rendering issue where the player's arm model becomes misaligned upon loading any shader pack. The issue persists across multiple different shader packs.
The problem is only visible in first-person view, where the arms appear shifted forward in a north-easterly direction. The arm positioning appears normal in third-person view.
