Hi Bruno, I am using Texture2DArray heavelly and it is not buggy ... I am not a guru on this, but the issues I faced as what Sebastian mentioned, you have to have the images for the slots the same size and what I faced when working with it was it was working only if I fill the slots sequencially. Maybe if you post a code we can look at
