OpenGL - Minecraft Flywheel indirect draw causes atio6axx.dll crash or missing geometry in Java applications

[EucatastropheMC]

I see this issue has been posted previously, but the driver is different, and I have more information available, so I am creating this issue instead of posting to the old one.

In Minecraft Java Edition, using the Flywheel rendering engine (used by the Create mod) reliably crashes the AMD OpenGL driver atio6axx.dll when placing blocks rendered by Flywheel. Switching to Flywheel's instancing backend prevents the crash but causes rendered geometry to become invisible, despite objects still existing logically (collision and simulation remain active).

System information:

• OS: Windows 11, 64 bit Build 26100
• CPU: AMD Ryzen 7 7800X3D 8-Core Processor
• GPU: AMD Radeon™ RX 7900 XTX 24GB
• GPU Drivers Version: Adrenalin 26.1.1

Java information:

• JRE version: OpenJDK Runtime Environment Microsoft-11369865 (17.0.15+6) (build 17.0.15+6-LTS)
• Java VM: OpenJDK 64-Bit Server VM Microsoft-11369865 (17.0.15+6-LTS, mixed mode, tiered, compressed oops, compressed class ptrs, g1 gc, windows-amd64)
• Runtime environment problematic frame: # C [atio6axx.dll+0x6d5278]

Generated error log: hs_err_pid30272.log

This issue is acknowledged in Create's repo and in Flywheel's repo.

The crash occurs on the render thread when LWJGL invokes glBindBuffersRange, which then crashes inside the AMD OpenGL driver (atio6axx.dll).

According to the JVM error log, the OpenGL call originates from Flywheel’s indirect rendering backend during instance buffer binding and culling, specifically from the following stack frames:

org.lwjgl.opengl.GL44C.glBindBuffersRange
dev.engine_room.flywheel.backend.engine.indirect.IndirectBuffers.multiBind
dev.engine_room.flywheel.backend.engine.indirect.IndirectBuffers.bindForCull
dev.engine_room.flywheel.backend.engine.indirect.IndirectCullingGroup.dispatchCull

Repro steps:

• Install Java
• Install Minecraft Java Edition
• Open the launcher and launch version release 1.20.1
• Close Minecraft
• Install Minecraft Forge 47.4.10 for version 1.20.1 from the official Forge downloads page
• Open the launcher and launch version Forge 47.4.10
• Click Mods → Open mods folder (or similar)
• Close Minecraft
• Download Create 6.0.8 for mc1.20.1 from their official CurseForge page
• Place the downloaded Create 6.0.8 for mc1.20.1 into the folder opened in step 7
• Open the launcher and launch version Forge 47.4.10
• Click Singleplayer → Create new world → Set game mode to Game mode Creative → World (at the top) → Set world type to superflat → Create world → Once it is finished loading, open the inventory (default key is E) → Click the compass in the top right to search, and search: cog → Left-click the item Cogwheel from the results and left-click an open slot in the hotbar → Exit the inventory and place the cogwheel on the grass by using right-click while holding the item in your hand → Game crashes and generates error log

These issues have been fixed internally, it will take some time to be included in the official Adrenalin drivers, once the fixed patches are included in the official Adrenalin driver, I will notify you for verification.
