When applying trimming to armors, the side of the 3D texture when in the player's hand causes Zfighting between the trim and the original model.
The test has been done with the wayfinder trim on netherite boots and pants with gold trimming, but it probably affects other trims that have trimmed pixels on the side of the item.
