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)
