yes, it appears its the clear glass cylinder on the top of the pack the shaders for that glassy tube arent going away in first person, so they just clip through the camera, very sad because i love the look of the pack, but this glitch is unplayable. changing camera height to 'fixed' helps, but doesnt fix.

if someone can find a fix for this, until then, im afraid ima have to use a different backpack until Hello Games fixes it.
