World becomes semi transparent, non-liquid blocks will all assume the same texture, entire screen starts flashing. Will stop if paused using the 'esc' key, but restarts when reentering the game.

What I expected to happen was a normal experience on minecraft, all game modes.

About five or ten minutes after entering a world, my world begins flashing rapidly, every block changes into the same texture while flashing. The world, apart from the patchy texture every block has, becomes transparent. It will start and stop irregularly, but every time it restarts the time period it flashes during lengthens.

Steps to Reproduce:
1. Log into minecraft.
2. Open a world of any game mode.
3. Play for five to ten minutes, then the flashing will start, quickly stopping at first, but then gradually it lengthens every time it happens.
