PCSX2 version:
Development Build v1.7.0-111.

PCSX2 options:
Defaults (out-of-the-box fresh install). Worse with HW renderer, but seems to occur in SW to a lesser extent.

Plugins used:
Defaults.

Description of the issue:
The mansion in Twilight Town at the beginning of the game, where the first fight against the Dusk is, has what I believe are z-fighting issues. As the camera moves, the textures for the mansion's walls flicker over its windows. It's visible when walking around the area, but most noticeable in the cutscene immediately preceding the fight.

How to reproduce the issue:
Play the game as normal until you reach the first Dusk fight, then watch the mansion.

Last known version to work:
Unknown, but the issue is also present in Stable Build v1.6.0.
