    Seems ok in 5.6.2f1. Nothing in the release notes. No answer from the Unity Team. They need to put some effort on this.

    I can also confirm that this issue still exists in 5.6.1f1.

    updated to 5.6.1f1, deleted my Library folder, and the issue is still there. if this was at one point fixed, it's a regression

    I have the same problem - textures with BC7 loose the alpha when packed with the sprite packer during play/build time
