whenever I load up a game of minecraft in any of the new snapshots the graphics seem to flicker. ie: every few seconds there is a pure white frame. this happens everytime I run any of the snapshots, both fullscreen and windowed. none of the video settings have much of an effect, although lowering mipmap does seem to reduce the flickering to every 10-15 seconds or so. It also occurs in 1st person and in both 3rd person views. the problem also persists when the game is paused. the flickering starts as soon as a world is loaded and persists until the world is closed again.
