There is a gap between the fill and the line of a shape.

When I draw a circular shape on a white background and set the fill and line, the background is visible between them. The lines are drawn on the outside, but there should be no gap between the line and the fill.
The first image shows the program monitor panel where the shape was drawn, and the second image is a magnified view of a portion of the shape, which shows that there is a gap and the background is visible.
