Code for reproducing the problem

class BugReport02(Scene):
    def construct(self):
        mathtex = MathTex(r'\text{MathTex: 波源相对于介质运动，}v_s', font_size=70, tex_template=TexTemplateLibrary.ctex)
        text = Text(r'Text: 波源相对于介质运动', font_size=70, ).next_to(mathtex, UP)
        tex = Tex(r'Tex: $v_S,u_S, w, \omega$', font_size=70).next_to(mathtex, DOWN)
        self.add(mathtex, text, tex)
