The last few characters of the output text effect in save mode(-w) are blurred

[xiaoxuz]

from manimlib import * class Test(Scene): def construct(self): circleRadiusLabel = Text("r=4m", font_size=36, color=RED) self.play(Write(circleRadiusLabel))

This is my code.
I found that this code works fine in interactive mode, as shown in the following figure

But after saving it as a video, the last few characters of the text in the animation are blurred after playing, and it feels like SVG has not finished rendering, as shown in the following figure.

Have you ever encountered this problem? I feel that this problem is easy to occur

I am using tag v1.6.1
