BGFX Shutdown Freezes on Direct3D12 with Intel GPU

[CDevJoud]

Description

While learning BGFX, I encountered a bug where the application freezes when calling bgfx::shutdown() after initializing BGFX with the following settings:

init.resolution.width = vm.width;
init.resolution.height = vm.height;
init.resolution.reset = BGFX_RESET_VSYNC | BGFX_RESET_MSAA_X8;
init.type = bgfx::RendererType::Direct3D12;
init.vendorId = BGFX_PCI_ID_INTEL;

The application stops responding, and the output debugger shows the following message:

Expected Behavior

The application should exit cleanly after freeing all allocated resources.

Steps to Reproduce

1. Initialize BGFX with the settings above.
2. Call bgfx::init(init) to initialize.
3. Run the application and then call bgfx::shutdown() to clean up.
4. Observe that the application freezes or gets stuck.

Environment

• OS: Windows 11
• GPU: Intel Integrated Graphics, Intel UHD

Additional Context

• I tested the same code with other renderer types (bgfx::RendererType::OpenGL, bgfx::RendererType::Direct3D11), and they exited fine.
• Testing on another GPU (NVIDIA RTX) with RendererType::Direct3D12 also worked without issues.
