2018.2 Building with default compression method causes black textures (works well with LZ4)

After updating to Unity 2018.2, when we build the game causes black textures or black materials, when we are using Default compression method in build settings.

By changing the texture size, in game, to quarter or half resolution, some materials still has black textures.
Also changing the textures quality, causes different black textures randomly.
Its like everytime i change the texture size or quality other materials are affected, randomly!

This issue is not present when building the game using LZ4 or LZ4HC compression method in the build settings.

It seams to be a texture streaming/loading issue but we are not sure.

Also the issue is not present in the Editor.

Reproduced with all Unity 2018.2.x versions.
Unity 2017.x works well as well.

 

Got same problem when using "QualitySettings.SetQualityLevel".
