If the character is walking towards/away from gate or door, a single-right click registers as multiple rapid-fire clicks. It is therefore very difficult to open doors/gate as you approach them.

This does not occur if the character is stationary when the right-click is attempted.

I use gate/doors as example because this is where the behaviour is most often noticed. But it applies in general to all right-clicks while in motion (placing blocks etc)

This behaviour was introduced very recently.
