I don't think it is to do with speed of mouse click.  The mouse should
send one event when you click and another when you release.  I wonder
whether it is sending additional click operations or something along
those lines.  In a terminal run
xev
that will open a little window and show you events in the terminal
itself.  Move the mouse over the little window then click the mouse
button.  Each time you click you should see a down event and then a
release event when you let go.
