Happens only at the first boot-up.Likely to be a off-sync vblank issue.

My research shows 0.133u1:

"NMK16 driver clean ups. Merged some of the duplicated code in nmk16.c,
and attempting to handle the larger tilemaps used by Thunder Dragon 2,
Rapid Hero and Macross 2 in a more correct way. This has fixed some
glitches in the intro of Rapid Hero without breaking the ingame
graphics. [David Haywood]"

It think it's safe to credit Haze :)

I think i twaeked the interrupt generation a bit until it didn't happen, as the interupt generation is still mostly unknown (and the only details we have about the hardware clearly don't apply to every game, because they're different PCBs) I'm not sure I'd say it was fixed properly, although it doesn't happen anymore.
