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

https://reddit.com/link/1r53ta2/video/b2ktm5afrkjg1/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 fine 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?
