AMD OpenGL driver (atio6axx.dll) access violation when enabling rendering on Rembrandt iGPU #586

Description

@Aenora5146

Environment

  • Minecraft: 1.21.11
  • Fabric Loader: 0.19.3
  • Fabric API: Latest
  • Sodium: 0.8.12
  • Voxy: 0.2.16-beta

Also reproduced on:

  • Voxy 0.2.15-beta

Hardware

  • Laptop: ASUS Vivobook 15 M1502NAQ
  • CPU: AMD Ryzen 7 170 with Radeon Graphics
  • GPU: AMD Rembrandt integrated graphics (PCI Device ID: 1002:1681)
  • Driver Version: 32.0.21032.24 (AMD Adrenalin 25.10.32)

Operating System

  • Windows 11 25H2

Description

Enabling Voxy rendering immediately causes the renderer to freeze.

The game itself continues running (audio continues, mobs continue attacking, etc.), but the screen freezes and flickers continuously.

Sometimes the game remains frozen indefinitely.
Sometimes it crashes to desktop.

The issue is fully reproducible.

Reproduction

  1. Create a fresh Fabric instance.
  2. Install only:
    • Fabric API
    • Sodium 0.8.12
    • Voxy 0.2.16-beta
  3. Launch Minecraft.
  4. Enable Voxy rendering.

The renderer immediately freezes.

Things already tested

  • Fresh Fabric instance
  • No other mods installed
  • Fresh world
  • Latest official AMD driver
  • ASUS official graphics driver
  • AMD compatibility patch
  • Voxy 0.2.15-beta
  • Voxy 0.2.16-beta

All produce the same behaviour.

Crash Information

Prism Launcher exit code:

-1073741819

Windows generated a crash dump.

WinDbg reports:

Failure Bucket:

Faulting module:

Exception:

Driver version:

The crash occurs inside the AMD OpenGL driver while Voxy rendering is being initialized.
