But you shouldn't rely on game mechanics which are implemented in snapshots. And if you want a small 1 tick pulse generator (on the rising edge) you could use this: http://imgur.com/kSz9idp

True, but would it be to much to fix the sporadic outputs and keep the pulse.
Both I and and a lot of others that make videos, worked on redstone machines that used this pulse in a new way that cant be reproduced now, mainly with the way it interacted with dispensers.

But it is inconsistent. You would aspect that a comparator would have a logical output which only depends on its input and not on time besides the fact that the output has a delay, so not changing output while there is a constant input.

I agree with Tomas, This was a nice addition to some compact redstone with simple and advanced uses.

I want this back, it was awesome

Confirmed in 13w02b.

This bug needs a better title description.

I experienced the same bug. It seems that when the comparator is in subtraction mode and there is an input from the side but none from the normal input, as soon as this input changes the comparator first acts like a normal comparator (not in subtraction mode) and repeats the input, however 1 tick later it does output the correct subtracted output strength.
