I apologize for my poor english.

1- Playing in survival mode, world started in 16w03a, I play last version, now in 16w04a
2-Every time i try to restart the game, If i return to the main screen and try to play, a "image jam" (random shards of the map appear and disappear) is all i can see,
3-If I close the game and completely restart the program, the problem disappear.
4-The problem begins in 16w03, and continues now.

Attached Video (divx, 24 seconds) with capture of the problem.

Thanks you-
