Extraneous Lines on Sphere in OpenGL

Description of bug / unexpected behavior

Some OpenGL Mobjects have extraneous lines both on and the mobject and off. The sphere demonstrates this.

Expected behavior

To not have extralines like in cairo.

How to reproduce the issue

Code for reproducing the problem

```py %%manim --write_to_movie --renderer=opengl -v DEBUG -ql GL class GL(Scene):#bug def construct(self): axes = ThreeDAxes() sphere = Surface( lambda u, v: np.array([ 1.5 * np.cos(u) * np.cos(v), 1.5 * np.cos(u) * np.sin(v), 1.5 * np.sin(u) ]), v_range=[0, TAU], u_range=[-PI / 2, PI / 2], checkerboard_colors=[RED_D, RED_E], resolution=(15, 32) ) self.add(axes, sphere) self.play(self.camera.animate.scale(0.5),run_time=3) self.play(self.camera.animate.scale(2),run_time=3) ``` ## Additional media files
