Graphs not rendering properly

[matiaspalumbo]

Hello, I've been recently trying out on Manimgl the code from example_scenes.py, and I've encountered that some graphs don't show up properly in the render. More concretely, there are patches of the curves that seem to be "skipped", or not rendered properly (particularly on the sine and parabolic graphs). I was't able to fix this. Below is the code and a screen recording of the graphs and the scene in question.

    def construct(self):
        self.wait(10)
        axes = Axes((-3, 10), (-1, 8))
        axes.add_coordinate_labels()
        self.play(Write(axes, lag_ratio=0.01, run_time=1))
        sin_graph = axes.get_graph(
            lambda x: 2 * math.sin(x),
            color=BLUE,
        )
        relu_graph = axes.get_graph(
            lambda x: max(x, 0),
            use_smoothing=False,
            color=YELLOW,
        )
        step_graph = axes.get_graph(
            lambda x: 2.0 if x > 3 else 1.0,
            discontinuities=[3],
            color=GREEN,
        )
        sin_label = axes.get_graph_label(sin_graph, "\\sin(x)")
        relu_label = axes.get_graph_label(relu_graph, Text("ReLU"))
        step_label = axes.get_graph_label(step_graph, Text("Step"), x=4)
        self.play(
            ShowCreation(sin_graph),
            FadeIn(sin_label, RIGHT),

        parabola = axes.get_graph(lambda x: 0.25 * x**2)
        parabola.set_stroke(BLUE)
        self.play(
            FadeOut(step_graph),
            FadeOut(step_label),
            ShowCreation(parabola)
        )
        self.wait()
        dot = Dot(color=RED)
        dot.move_to(axes.i2gp(2, parabola))
        self.play(FadeIn(dot, scale=0.5))

        x_tracker = ValueTracker(2)
        f_always(
            dot.move_to,
            lambda: axes.i2gp(x_tracker.get_value(), parabola)
        )

        self.play(x_tracker.animate.set_value(4), run_time=3)
        self.play(x_tracker.animate.set_value(-2), run_time=3)
        self.wait()

I tried the code and I have no problem. Does the issue still exist with the most recent version of manimgl ?

Hello, it happens the same to me with the last version of manim v1.3.0, I simply run the example_scenes.py on UpdatersExample and i get lots of lags on the text and on the bracket.

Edit : config = python 3.10.1, Windows 10 64bits,

Hi, did you figure out how to fix that? @Benarl
