Description :
Hoppers don't work properly if they contain 2 types of item.
What happened :
Let's put items (emeralds) in the hopper on the right.
If the bottom hopper is empty : emeralds go in.
If the bottom hopper has 1 slot with emeralds and 3 slots with snowballs : no problem.
If the bottom hopper has 1 slot with emeralds and 4 slots with snowballs : it doesn't work anymore and all emeralds go in the chest.
So basically it breaks all the hopper filters players have made.

Hey man! Looks like you got the bug before me! I just made an explanation about it in my bug report: MC-41537
I will edit my post and add your explanations and pictures ! 🙂
And also I'll change a bit my title. I didn't know that it was broken even filling the hopper with the same type of item.
Actually I prefer your version; so if a mod can close my report and reopen Fernando MK's one, I think it is better !
At the ticket MC-41537 there isn't any screenshot and only a very short description.
There are screenshots here http://imgur.com/a/BXF4L and his ticket is more accurate since he has seen what was the real issue with hopper (not having an emply slot) whereas I didn't find something really clear but just that "hoppers are broken".
(By the way correct me if I make mistakes, I'm not English).
At users request: Reopened MC-41537 and resolved this as duplicate.
Confirmed.
A much simpler test for this is to have a non-bottom-funneling hopper with items in it above a hopper filled with 1 of the same item in every slot. It will not pull items into it, however if you increase any stack to 64, or create an empty slot, it will fill as it should. An exception there is if you remove the first item in the bottom hopper, it will move 1 item and then stop.
Something to note here is this issue does not exist if the above hopper is funneling into the lower one, only when the bottom hopper is stealing them from the upper hopper. In my described example, I use only 2 hoppers, so it isn't a timing issue.
