Trident is invisible in the players hand in first and third person, unless in first person the player is within range of a block or entity. Or sometimes randomly starts flickering or disappears.
Possible example steps to reproduce, doesn't trigger every time:
1. Create a flat world creative.
2. Equip a trident in first person in creative or survival.
3. Notice the trident is not visible, unless within range of a block or entity (hit range ~<5 blocks).
4. Switch to 3rd person and notice the trident is not visible at all in both front and back view.
When holding the trident in game, it doesn't show it. But sometimes it like shows it but not being held correctly. But for me its invisible
The bug was fixed on version 220.127.116.11, but still exists on the non beta version (18.104.22.168 and 1.2.16)
