There is a visual bug affecting enchanted armor in Minecraft where a solid blue box appears around the character when any enchanted armor is worn. This issue does not occur with non-enchanted armor.

When equipping any piece of enchanted armor, a blue box completely covers the character model. This visual glitch is consistent across all types of armor (helmets, chestplates, leggings, and boots) as long as they have any enchantment. Non-enchanted armor displays correctly without any visual issues.
