The particles for landing on a block are centered on the block you land on, even if you only catch the corner. Logically the particles should come from the players feet, but instead they come from the center of the block. This makes the whole effect look very strange.

Even works with water "blocks" thou you actually can't land on them (they are a pixel lower than normal blocks) - http://i.imgur.com/9BDqtJF.png & http://i.imgur.com/WmqpbeN.png (kinda hard to see in the second one, but shows that pretty good)
Confirmed.
