Multiple onUpdate (x16 at a time, at every xx:xx:00)

A new bug appeared: onUpdate() is called by the system 16 times every time the seconds reach 00 (which normally triggers onUpdate() once).
I'm currently using CIQ 3.0.7 buy it's also true for CIQ 3.0.6.
Just to check, I created a new standard watchface with settings. Added an onUpdateCount variable that I increment in onUpdate().
var onUpdateCount = 0;
class WatchfaceDefaultView extends WatchUi.WatchFace {
function onUpdate(dc) {
onUpdateCount++;
var t = System.getClockTime();
System.println(t.hour.format("%02d") + ":" + t.min.format("%02d") + ":" + t.sec.format("%02d") + " onUpdate " + onUpdateCount);
/* etc... */
}
}


Here is what the console looks like:
00:02:28 onUpdate 1
00:02:28 onUpdate 2
00:02:40 onUpdate 3
