Summary	07883: BGFX: -bgfx_backend d3d9 not working
Description	The bgfx backend d3d9 now produces a black screen on some games, or really bad graphics.
Steps To Reproduce	>mame -video bgfx -bgfx_backend d3d9 pacman black screen >mame -video bgfx -bgfx_backend d3d9 superx black screen >mame -video bgfx -bgfx_backend d3d9 mvsc very bad graphics >mame -video bgfx -bgfx_backend d3d9 invaders black screen (with screen 0 standard), but it works with (Midway Upright Artwork) Actually, invaders is weird. If bezels and backdrops are off, there's no game graphics. Turn on either of those, and it's working again.
Additional Information	Other backends are fine (d3d11, d3d12, vulkan, opengl)
