Texture error in the worlds - Rain (Bugs only my device)

Hi, well here's my second mistake, I repeat that all this is translated into google translator, my second mistake is that in a world where it rains all looks bad texture map in general whereas if it stops raining looks good I that will be by the movement of the rain and animation in addition to servers, I know you do not do servers suppose, but on servers is equal without rain do not know if it's because there are so many players or much movement, I tried to put many animals to see if it was the same but nothing happened. this is my second mistake.
