Issue with my friend’s server

While playing Minecraft Bedrock Edition on an iPad, my friend and I encountered little visual glitches while he received a series of severe visual and audio glitches. Hus screen began flashing pink, and the game failed to load properly. After force quitting and reopening, the server photo appeared pitch black. In-game, he experienced strange terrain generation including an arrow-shaped line of unloaded chunks pointing toward a village with no Iron Golem (on Peaceful mode), and a white orb flashing in the distance. He also heard persistent humming and synth-like sounds even after closing the app. These issues suggest a possible rendering or memory corruption bug, potentially tied to the seed or platform. He’s restarted the device and reinstalled the app, but the anomalies persist.
