Dark Cloud Interlacing (Comb )

You can see it just by turning the camera while in the first town. I tried in standalone pcsx2 and there was no ghosting.

LRPS2

Start by reproducing the combing or ghosting in the first town with the reported LRPS2 settings, especially the paraLLEl-GS renderer, and compare it with standalone PCSX2. The issue names no source file or test, so locate the rendering and interlacing entry point first. Done means the visual artifact is absent while turning the camera.
