Summary:
If you try and open a door, gate, or trapdoor when moving, it rapidly opens and closes, often meaning the player cannot get through.

Repro Steps:

Place a fence gate
Walk towards it
Open the gate whilst moving

Observed Results:
The gate opens and closes very rapidly.

Expected Results:
It should only open or close once, unless the player holds the interact button for a long time.

Screenshots/Videos attached: Yes

Original Description:
When I use the mouse to place blocks or use items, I experience what I see as an input bounce. This input bounce is not experienced outside of Minecraft. I tried several mouse with the same results. I have only experienced this phenomena since upgrading to the 1.2.1 version of Minecraft. When I try to open gates they often times open and close so fast and so many times that I am unable to pass through the gate.
