Resolution Note (2018.3.X):
On OpenGL ES 3 and higher there is no Alpha8 texture format. We use two extensions to provide the same functionality. One of those extensions (GL_EXT_texture_swizzle) doesn't work correctly on some drivers on Mali GPUs (see https://issuetracker.unity3d.com/issues/es3-dot-0-slash-3-dot-1-when-using-an-alpha-8-image-as-an-alpha-mask-on-android-6-dot-x-devices-with-mali-the-mask-doesnt-work).
