Magical Night Dreams Cotton 2 (Japan) // Some garbled graphic

[Zet-sensei]

On Stage 2, we can see some incorrectly rendered stripes on the background.

After some tests, the VDP2 NBG0 plane is affected by the bug. We can see 2 horizontal stripes incorrectly rendered too at the top and bottom of the image - which are mostly hidden by the other planes during a normal gameplay.

Toya & Kuba-J have seen the bug reappearing on the 2024-04-03 version of the core.

I will test once more also on my side and update further.

EDIT : I can see the issue too but I needed to remove my video filters.
