Pinocchio - Trembling HUD glitch

[a-barone]

S32X Core version:
Release 20220607

Hi!

The Pinocchio prototype exhibits a trembling HUD when horizontally scrolling the screen only on the S32X core; it doesn't happen on real hardware. The videos I recorded were with the game running at 60Hz but the issue also occurs at 50Hz with the S32X core.
I recorded footage of the S32X core running side-by-side with a real Genesis 32X setup:

And here is a recording focused only on the S32X Core and zoomed in:

I used this ROM for the tests:

To trigger the issue: Hud ( pinocchio life count ) tremble when scroll speed accelerate or decelerate, at any point in the game. Very visible at game start too.

tried, still there.
Just as a log, the issue is so minor that not sure anyone care.
Also probably the last active reported issue
