Bump? Thanks to someone for moving my thread to the correct category, so
hopefully I'll get some sort of response soon :)

It would be helpful if you were able to get an apitrace [1] of the problem.

Thank you for replying!

My apitrace file is unnaturally large (418MB) so I uploaded it to Google Drive
instead of this site. The apitrace log is also large (24MB), so it's also in
the shared folder.

--- Comment #5 from Timothy Arceri <t_arceri@yahoo.com.au> ---
There is a bug in one of their generated shaders.

 error: #extension directive is not allowed in the middle of a shader

Some other drivers allow extension to be defined mid shader but this is invalid
according to the OpenGL spec. You can see the problemn shader below:

#define EMULATION_UBO_BINDING 4
#define CBUF_BINDING_1 5
#define CBUF_BINDING_4 6
#define CBUF_BINDING_12 7
layout (lines) in;           <--- This needs to be after #extension
#define MAX_VERTEX_INPUT 2
#extension GL_ARB_separate_shader_objects : enable


This should be reported to the yuzu devs. For now you can try work around it by
setting the below environment variable when running yuzu. Let me know if this
fixes the issue for you.

allow_glsl_extension_directive_midshader=true
