Problem with Incorrect Texture Rendering When Using .atls Files via Asset Pack

[Tenderfeel]

In a demo project created using "Create Pixi (Creation Templates)," I tested the display of SpineBoy. However, when rendering a Spine instance using .atls files loaded through an Asset Pack, the rendering was incorrect.

The edges around the character appeared jagged and rough.

Is this issue caused by a configuration problem or a bug in the Asset Pack? If it's a configuration issue, could you please share a solution to resolve it?

Node.js: v23.3.0

I have the same bug. But mostly with my own spritesheet and atlas is compressed. Then I get the same artefacts around the edges of the figure at @0.5x or whenever it has run through the assetspack'er.

Disable "Premultiplied alpha" in the Spine export as assetpack doesn't seems to support it
