seems only to affect the US Version, as everything is fine with my PAL Version.

by "which wasn't there before", do you mean that the bug did not occur in a
previous version of the emulator ?

I just checked and :
1) it's not constantly happening when you jump, most of the time but not always
so it's easy not to notice it
2) it only happens in that part, when standing on the top platform
3) it happens in Fusion / Gens too
From debugging, when jumping, the game do some VRAM updates during active
screen, which is the cause of the pixel garbage.
It's probably a bug in original game with the way scrolling is handled at the
top of the screen (only seen when jumping from the top platform at the start)
and most likely happens on real hardware as well (if it was caused by emlator
inaccuracy, you would have an entire line of garbage, not a bunch of pixels).
It does not happen on PAL system because VBLANK has more time and those extra
VRAM writes are completed before active display starts.
