Grass and flowers flicker or glitch in Android Bedrock Edition 1.21.100.6

When playing in a normal world on Minecraft Bedrock Edition for Android, grass blocks and flower textures start flickering rapidly, as if they are glitching. This happens even when no texture packs or shaders are applied. The issue appears randomly when moving around, especially in grassy areas with flowers.

Steps to Reproduce:

1. Launch Minecraft Bedrock Edition on Android

2. Create or load a world with default settings (no texture packs or shaders)

3. Walk around grassy areas with flowers

4. Notice grass blocks and flowers flickering intermittently

Expected Result:
Grass blocks and flowers should render normally without any flickering.

Observed Result:
Grass and flower textures flicker rapidly, breaking immersion and making it uncomfortable to play.
