Crash: #extension directive is not allowed in the middle of a shader
See original GitHub issueDescribe the Bug
I’ve been able to avoid the crash by deleting this section of code from the shaders inside the Create and Flywheel .jars:
// optimize discard usage
#if defined(ALPHA_DISCARD)
#if defined(GL_ARB_conservative_depth)
#extension GL_ARB_conservative_depth : enable
layout (depth_greater) out float gl_FragDepth;
#endif
#endif
The issue seems to be that Mesa3D does not like #extension being in the middle of a shader, rather than at the top.
Reproduction Steps
- Try launching minecraft with latest Create and Flywheel for 1.18.1
- The game crashes
Expected Result
Minecraft wouldn’t crash.

Fixed in latest versions of Create and Flywheel.
Thank you, the work around worked for my friend running Fedora 35 with an AMD gpu.
