z-fighting and model problems

In Minecraft Bedrock Edition, during normal gameplay, there's a Z-fighting issue with the textures of some models, like the player. However, this Z-fighting doesn't seem to affect the player model in the inventory. Apparently, the inventory rendering is fine, but the in-game rendering shows many textures and models with the Z-fighting problem. It would be great if they fixed these minor visual glitches. Additionally, the new blocks they're adding have slight modeling errors, such as lanterns where some faces aren't properly aligned. These errors are becoming increasingly common among new items.
