Summary	07434: mhavoc: Experiencing graphics glitches in mhavoc on i9-9900K/Nvidia 1080 GTX since v0.174
Description	I am experiencing graphics issues in Major Havoc. Sprites flicker and ships disappear, especially in board 2, where the mothership and white train of ships disappears. Walls of the maze on board 3 are invisible, making the maze board unplayable. Also, in current MAME 0.213, there is a minor glitch where the line priority is wrong causing the tunnel lines to draw over the ship lines at the beginning of the game. The ship should be in front of the tunnel. I did not regression test this minor issue. It is not present in 0.174.
Steps To Reproduce	Any mame after 0.173 seems to show this problem. Mame 0.173 and prior works properly. Launch the game and play. It doesn't matter if you have HLSL enabled or not.
