Dynamic Smooth Arc with rounded ends

[ebarons]

Hey,
I'm trying to make the same thing as in the Arc_Meter_Demo from Examples, but have the ends be rounded by using drawSmoothArc (true as the last variable).

However, the result is as seen in the picture with BG color as contour around every "generated point" as you can see in the picture below:

Is there any way to achieve a drawn antialiased arc with rounded ends with the current version?
(using this for a countdown timer, drawing the arc as a visual countdown adjusted to the chosen time)

PS. extremely thankful for this library!
