segmented-arc sometimes renders the gaps between the segments

[AmoebeLabs]

Bug description

While observing the animation on the segmented-arc, it appears that the gap between the arcs is partially filled while going from one arc part to the next arc part and vice-versa.

It is not that the full gap is filled temporarily, but just a part of the gap. Must be some calculation going wrong.

Will be a difficult thing to fix, I'm afraid...

(Optional): Suggested Solution

None.
