Summary	05324: cubeqst, mach3, usvsthem and clones: There's a blank screen in certain places in the video
Description	There's a blank screen in certain places in the video. Screens like the high scores and the cube no longer shows up. The screen goes blank after the intro then it shows the laser-disc backgrounds . After inserting coin, the selection screen where you select your skill level like beginner or advanced no longer shows up and the cube where you maneuver your ship to choose levels is now a blank screen. After the blank screen, the only thing showing up is the laser disc backgrounds and the ship and enemies you controlling after that everything just goes blank. When you lose all lives, the game over screen is blank and does not show up. After only the laser-disc background intro and credits is showing and that's it. Everything works fine and perfect in MAME 0.149. But problems occurred on MAME 0.150

No.09876 Tafoid Administrator Oct 8, 2013, 23:49	I did some regression testing and testing all LD games and discovered the following: -video ddraw works fine for all LD games. -video d3d is an issue on 3 of the 6 LD games (cubeqst, mach3, usvsthem). It works in parts where the LD and regular gfx are both enabled. When LD is disabled (but regular gfx enabled) you get a black screen. This has been traced to r25068 where a number of MT bugs were fixed and other fixes were done. -HLSL behavior is a separate issue, it looks like, and predates this issue related to the changes. In a screen where LD is enabled and gfx are enabled you only see the gfx. When LD is enabled (but regular gfx are disabled) you get a black screen. I'll look for and log a regression if I find it.
