| Summary | 08976: x68000 [chorensa]: Right side of display repeated | ||||
| Description |
When running chorensa, the right hand side of the display is repeated. This is a regression between MAME 0.251 and 0.252. See attached file for visuals. |
||||
| Steps To Reproduce |
With MAME 0.252 .\mame.exe x68000 -rompath "..\x68000\bios" -nvram_directory "..\x68000\nvram" -nomouse -flop1 "..\x68000\disks\超連射68K.2hd" Note the corruption on the right hand side of the screen once the game has auto-loaded. Repeat with 0.251, see no corruption. |

| Additional Information |
I had a look through the commits list for x68k changes, but wasn't able to spot anything obvious. https://www.mamedev.org/releases/whatsnew_0252.txt |

From bisecting this, it appears to be a bgfx issue. Strange it only shows up in this game. Works fine with the -video d3d option. |

Right - looks like something in this commit broke it: https://github.com/mamedev/mame/pull/10858 Setting '-bgfx_screen_chains none' fixes it, the issue is present on all bgfx chains and backends I can try on my machine. |

Making the window full screen and then restoring it causes the issue to go away. |

Everything on the right-hand side exhibits the problem. >mame x68000 chorensa -video bgfx -bgfx_screen_chains crt-geom |

The bug can also be fixed by incrementing the 'screen' parameter directly in the chorensa game. The video attached demonstrates this. This was taken using my own MAME build for convenience. |

If it's of any use, this isn't resolved with the BGFX update proposed at https://github.com/mamedev/mame/pull/13054 |
