As a quick workaround without changing UPP code :

static void _DrawCircle(ImageDraw &iw, int xc, int yc, int r, Color c)
{
#ifdef flagGTK
	iw.Alpha().DrawArc(Rect(xc - r, yc - r, xc + r, yc + r), Point(xc + r, 0), Point(xc - r, 0), 2, GrayColor(255));
	iw.        DrawArc(Rect(xc - r, yc - r, xc + r, yc + r), Point(xc + r, 0), Point(xc - r, 0), 2, c);
	iw.Alpha().DrawArc(Rect(xc - r, yc - r, xc + r, yc + r), Point(xc - r, 0), Point(xc + r, 0), 2, GrayColor(255));
	iw.        DrawArc(Rect(xc - r, yc - r, xc + r, yc + r), Point(xc - r, 0), Point(xc + r, 0), 2, c);
#else
	iw.Alpha().DrawArc(Rect(xc - r, yc - r, xc + r, yc + r), Point(xc + r, 0), Point(xc + r, 0), 0, GrayColor(255));
	iw.        DrawArc(Rect(xc - r, yc - r, xc + r, yc + r), Point(xc + r, 0), Point(xc + r, 0), 0, c);
#endif
}

Notice the thickness of 2 in GTK mode, using the default (0 or 1) draws an almost invisible arc.
