Summary	08659: opengl, bgfx: All but one screen start minimized when numscreens > 1 and windowed mode is disabled
Description	Only when using opengl and bgfx video modes, setting numscreens to 2 or higher and having windowed mode turned off will only show one of the screens in full screen mode. The menu screen must be manually reached to see. Windowed mode works fine.
Steps To Reproduce	Open mame.ini. Set video to opengl or bgfx. Set window to 0. Set numscreens to 2 or higher. Start MAME. Only one of the (blank) windows will start in full screen.
