Tellusim StarWars 20221109 demo tracing crashes

When it's running outside apitrace it's extremely slow, but does work.

So Intel driver is aborting here.

Per the comments here, it seems the GPU is hanging.

It's hard to imagine why using apitrace would cause this.

The only smoking gun I see is the warning "hiding program binary formats (https://git.io/JOM0m)". Perhaps this causes the game to use different shader representation, which in turn triggers Intel GPU hangs.

See if the following patch for disabling ARB_get_program_binary suppression helps:

Not sure if it's the cause here, but indeed apitrace should be improved so that instead of filtering out all binary formats, it should filter out vendor specific formats, and leave vendor agnostic formats such as GL_SHADER_BINARY_FORMAT_SPIR_V_ARB.

Nevermind, GL_SHADER_BINARY_FORMAT_SPIR_V_ARB is about glShaderBinary, not glProgramBinary, and it's not being suppressed by apitrace anyway, so can't be related.
