Those lines are showing up because the old algorithm can't produce all possible values in the 0-1 range. 32 bits of internal state simply aren't enough for that

Those lines are showing up because the old algorithm can't produce all possible values in the 0-1 range. 32 bits of internal state simply aren't enough for that.
