animated_marker animation noise

[Bruno Oliveira <bruno manata oliveira gmail com>]

Hi, i have been developing my own application with libchamplain but i found out that animated markers are not rendered properly.

I tried compiling the included demo "animated-marker.c" and it renders the animated circle like in the image attached to this mail. What may be wrong?
