Paper Mario TTYD on Mac (Dolphin) – Weird Background Glitch with Widescreen + HD Texture Pack

https://reddit.com/link/1r53sjg/video/zv93qb63rkjg1/player

Hey everyone,

I’m playing Paper Mario: The Thousand-Year Door on Mac using Dolphin, with widescreen enabled and an HD texture pack installed.

The game runs good overall, but whenever I move, the background looks weird. It kind of shifts or distorts slightly almost like it’s not lining up correctly with the foreground. It’s most noticeable when walking around in towns or larger areas

Not sure if this is a widescreen hack issue, the HD texture pack, or some Dolphin graphics setting causing it.

Has anyone run into this before?
Is there a specific setting I should disable or tweak?
