Several graphical errors have been seen in this snapshot, including:
Gravel as it's a falling entity, turns assorted colors in a stone brick pattern.
Grass blocks held by endermen show the grass portion as white.
Seeds occasionally drop as the purple and black non-texture.
Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets, and it is easier for you to make multiple tickets than for the mods to separate them.
And please use the search function in the future as all of the issues are reported multiple times.
