Process memory leak with vulkan

[marko-ravnjak]

I'm doing some custom engine/rendering prototyping, and after setting up bgfx (i wanted to use vulkan backend) I noticed that process memory is steadily growing. After some testing I figured out that if leave backend to auto, the leak is gone. I tested direct3d11/12, opengl, and noop. They are all stable, only vulkan "leaks". I then built the 00-helloworld example, disabled the vsync (m_reset = BGFX_RESET_NONE) and ran the exe with and without --vk. Default d3d11 stabilizes the memory after a few seconds, but vulkan show constant growth, mostly small steps <0.5MB, but every minute or so, ~10MB jumps happen. Did anyone else notice this?
