[Bug Report] Severe Culling Artifacts & Missing Chunks on AMD Polaris (RX 580) - MC 1.21.11

Hello. I am reporting severe rendering issues on AMD Polaris architecture using the latest Voxy alpha build for Minecraft 1.21.11.
I have recorded a video (attached) demonstrating that while flying, chunks fail to render in a checkerboard pattern, showing the skybox through the ground. The chunks do not load even when waiting or getting closer, suggesting a culling calculation failure rather than a loading lag.

Visual Evidence:
Please watch the attached video. It clearly shows the issue is not performance-related (FPS is stable), but a rendering artifact specific to this hardware/version combo.

Environment:

Minecraft Version: 1.21.11 (Fabric)
Voxy Version: 0.2.9-alpha (for 1.21.11)
Sodium Version: 0.8.2+mc1.21.11
Java Runtime: GraalVM JDK 25 (ZGC enabled)

System Specifications:

GPU: AMD Radeon RX 580 2048SP (Polaris Architecture - No Native Mesh Shaders)
CPU: Intel Xeon E5-2680v4 (14 Cores / 28 Threads)
RAM: 32GB Total (12GB Allocated to MC)
OS: Windows 11 23H2
Drivers: Latest AMD Adrenalin Edition (25.8.1 for this card)(OpenGL 4.6)

Notes:

I suspect the Compute Shader fallback for Polaris/older AMD cards is failing to synchronize or properly cull geometry on 1.21.11. I have tried lowering geometry settings to Low with no success.

Hope this helps fix the support for older AMD cards on the latest versions!

Start by reproducing the checkerboard missing-chunk artifact from the attached video using the listed Voxy, Minecraft, Sodium, Java, GPU, driver, and Windows versions. Investigate the compute shader fallback and culling behavior on AMD Polaris, then verify that chunks render consistently while flying and approaching them without regressing supported hardware.
