Tubes with length 0 (machine precision) are rendered, and they appear to have a different CapForm as well. Why?
Graphics3D[{Hue[0], CapForm["Butt"], ViewVertical -> {0, 1, 0},
ViewPoint -> {8, -4, 2},
Table[Tube[{{i, 0, j}, {i,
Re[7*(1 - (Sqrt[(i/1.2)^2 + ((j - 5)/0.9)^2]/4.5)^2)^(3/2)],
j}}, 0.3], {i, -8, 8, 1}, {j, 2, 8, 1}]}]
