It was happening in my own code, but it also 100% reproduces for me in the examples. Simply build the examples, run and hit the window close button.

Seems to be something relating to it still being inside renderFrame() during bgfx::shutdown().

The Khronos reference page contains description of parameters and description of the behavior for every function. Wouldn't it be possible to add doc comments for the functions, so IDE can show it? I understand the function description is a bit cumbersome, as one description is usually related to multiple functions with similar functionality, however parameters description would help a lot.

Also optionally, if we make backwards incompatible changes to the config file we should notify users somehow. (E.g. changing defaults).

I wish doxygen documents is hosted online somewhere, it's kinda annoying just to clone and make my own copy to read documentations.
Anyway, this framework really helps me to make my own game engine.

Thanks.

BUT the original code (https://github.com/evanw/theta/blob/master/LICENSE.md) is GPL.

I can't look at the code => so I will implement it from his description.
