You are exporting your textures as straight alpha, but it seems that you have not adjusted your import settings to straight alpha in Unity. Please see the following section of the spine-unity runtime documentation:

I think I miss some important settings in spine that can make exported texture alpha channel is clean.

Why are you exporting as straight alpha but using it without Straight Alpha Texture enabled? Applying the wrong import settings in Unity will make your atlas look incorrect.

Why can't you enable the Straight Alpha Texture field Material property in Unity for Mobile? What problem did you encounter when you enabled it?

I should read documentation seriously. The problem is sovled.
