 Description   

When I feed a 1-tick pulse to a string of comparators, the first comparator lights up, but does not transmit a signal. Occasionally, the signal is carried through several comparators. No rule seems to affect this, not even chunk boundaries. When a single comparator followed by a redstone wire receives a 1-tick pulse, it works fine, as does a single comparator followed by a repeater.

This bug is still present in 1.5 on my computer, try making a one tick pulse generator with comparators, or use a redstone torch to made a one tick pulse and the comparator will not pick it up.

Unable to reproduce anymore, resolving.

Confirmed in 13w05a. I also did some more testing and it seems that a 2 tick pulse becomes a 1 tick pulse, but if you place 4 or more comparators after each other the pulse sometimes increases to 2 or 3 ticks. However 1.5 tick pulses seem to work fine.

I also noticed this and made a quick video about it: http://www.youtube.com/watch?v=dyo156gCrK4. This video also shows that the moment of placing a comparator also affects the way a chain of comparators update.

Confirmed in 13w02b.
