Hi, thanks for making this nice project available!

I've cloned the repository, ran make, and could successfully run all ./build/sample-* executables except the sample-framebuffer which outputs:

./build/sample-framebuffer 
sg_apply_pipeline: pipeline depth pixel_format doesn't match pass depth attachment pixel format
^^^^  SOKOL-GFX VALIDATION FAILED, TERMINATING ^^^^
sample-framebuffer: thirdparty/sokol_gfx.h:13735: _sg_validate_end: Assertion `0' failed.
Aborted (core dumped)

You need to provide more information on your system and backend. Also check #3
seems like it is related.

I've noticed that my fix for Metal for issue #3 broke the framebuffer sample and I have fixed in the latest commit. This issue was just in the sample, not in the library. Sokol app still need a way to disable depth stencil for all platforms though, so we can skip the overhead of creating the unused depth stencil image.

Thanks for reporting and letting me know that the framebuffer sample was broken.

Thanks for the quick fix!

Sorry for the missing system info.

For the record:
Linux, Kubuntu 20.04
Thinkpad T450s
Intel i7 Core, Intel 5500 integrated graphics
12GB of ram
(I assume the OpenGL 3.3 backend path is used - since everything is at the default)
