Hi @hujiaxu. I'm not sure I'm clear on the issue you are looking to solve. Can you explain a bit more about the jagged edge? Are you referring to the aliasing?

OK, i'm not sure it is the aliasing.

like red box in this picture.
And it's very abvious as i move camera, like in this video.

ktx2.mipmap.jagged.edge2.mp4

And then i use Model to load a gltf with this ktx2 texture, this phenomenon is not appear. I guess it's MaterialAppearance bug.

it's similar to #9746

Thanks @hujiaxu,

Yes, I think that is definitely aliasing. Since this is happening on non-model geometries, the fix will likely be the same as #9876, but applied to the MaterialAppearance as you mentioned.
