Sorry everybody for this stupid mistake, I knew it was an easy one... So I confirm that this fix and the previous one that you mentioned, the mipmap level that was supposed to be 0 instead of 1, make my sample work, thanks a lot Øyvind! At least I think I had correctly understood the graph part. Now I'll continue my tests in the main application. Best wishes for 2017.
