Texture glitch with chocapic shader

[S24gg]

Describe the bug

When using Chocapic13 V9.1 Extreme Beta 5 on MobileGlues,minecraft texture get very glitchy obsidian becom yellow ,lava become purple in colour etc.

The issue only happens with Chocapic13 shaders. Other heavy shaderpacks such as Derivativeand Complementary work correctly on the same setup without visual corruption.

This may be related to Chocapic13’s shadow filtering or framebuffer handling on Mali GPUs through MobileGlues.

To Reproduce

1. Launch Minecraft 1.21.4 using MobileGlues
2. Enable Iris + Sodium
3. Load Chocapic13 V9.1 Extreme Beta 5
4. Enter a world
5. Observe shadowed terrain and grass surfaces

Expected behavior

Terrain shadows should render smoothly without visible black dots, dithering, or grid artifacts.
