I've noticed this in mine too. To minimize this I set the function to wind shield and the fan to high. The hot/cold setting to hot. If that doesn't get rid of it fast enough, I put the a/c on. That usually clears it but it does take time sometimes especially with lots of people in the car. Once most of the moisture on the people evaporates and the air handler has a chance to remove it from the passenger space, the windows start to clear. For short jaunts, it isn't much help. The fan on high should at least keep the wind shield clear.
