I can confirm this report and add further information.

The issue doesn't always happen. It appears only in specific moments of the game, for example at the beginning of mission 2, 3 and 4. It also happens in the middle of some levels (see attached snaps for the specific points), always in the same places.

Oddly enough, it seems to appear almost always in some points (for example at the beginning of Mission 4) and less often in others (the beginning of mission 3).

Tested in mame 0.202
I've uploaded savestates of the beginning of each level.

Some indications of where the skip-scroll bug ocurrs in each level:
Mission2: right at the beginning, walk right
Mission3: right at the beginning, walk right
Mission4: After a few minutes playing the level (see attached image).
Mission5: I haven't been able to reproduce this one. Anyway, it is supposed to ocurr in the beginning of the level, after descending a little (see attached image). These bugs are random

Some evidence comparing mame emulation with the arcade pcb:

Mame emulation full gameplay:

Some of the reported skip scroll bugs can be seen in this gameplay:
5:57: Mission 3
11:36: Mission 4

Regarding missions 2 and 5 I haven't seen any scroll bug in that gameplay, but according to LastNinja2 these bugs are a random thing.
 

Original arcade pcb full gameplay:

In the arcade pcb none of the reported scroll bugs ocurr:
2:59: Mission 2
7:03: Mission 3
13:58: Mission 4
18:30: Mission 5
