Issue Summary:
Since recent beta versions and also in the official 1.21.80 release of Minecraft Bedrock, activating Vibrant Visuals or Deferred Technical Preview causes a severe visual bug when playing in first-person view on my Samsung Galaxy A15 (Android 14). The entire screen freezes and only the player’s hand is animated. In some cases, the screen gradually turns completely white.
Interestingly, this does not happen 100% of the time. In certain situations, the first-person view does work properly, for example:
When using the Aplok Guns mod, holding a weapon from the mod fixes the issue temporarily.
When using Actions & Stuff mod, equipping a torch in the hand also temporarily fixes the screen.
This suggests the issue might be related to how the first-person view is rendered while using Deferred Rendering or Vibrant Visuals mode.
This issue is being tracked at MCPE-217108.
