Confirmed breaking version and taking daily builds from there isolated the likely breaking commit:
https://github.com/mamedev/mame/commit/b91b3be70c22839ccd41381d6a7596de509b7c5e
 New device: Data East IRQ Controller

Used by games in the cninja and deco32 drivers. This implies proper
VBlank IRQ ack for all games now. Also added and improved raw screen
parameters for various games.
