Research direction

Reproduce the issue in a new Stride game on Android 13 by enabling Generate mipmaps for the Skybox texture, then compare the Android result with the editor scene. Investigate the skybox texture and mipmap handling involved in the Android rendering path; done means the skybox renders correctly with mipmaps enabled while preserving the documented workaround behavior.
