Good afternoon, how are you? It is giving this bug with the clouds, on my pc and some youtubers pc that make minecraft videos too, in which the clouds are like this, according to the image that is attached. When disabling "fabulous graphics" and putting them in detail the error is corrected and is became "normal", however, this error is in pre-realease 4, because in pre-realease 3 it did not give this bug.
Also, in the option of controls the Portuguese translation "swap item with offhand" is in English, which should be in Brazilian Portuguese "segurar item com a outra mão" or something like that, since pre-realease 3.
I thank you for your attention, Leandro.
