Transforming Tex with opengl renderer results in "Exception: Could not find a ring to attach"

[yang-tsao]

Description of bug / unexpected behavior

When I try to transform Tex with opengl renderer, I encountered "Exception: Could not find a ring to attach". With the default cairo renderer everything worked fine.

Expected behavior

I expected my code will run even if I choose the opengl renderer.

How to reproduce the issue

Code for reproducing the problem

Run with the --renderer=opegl flag, and you'll encounter "Exception: Could not find a ring to attach". Without the --renderer=opegl flag, everything works just fine.

from manim import *

class Tran(Scene):
    def construct(self):
        A = Tex("A")
        B = Tex("B")
        self.play((A, B))

is this really your complete code?

from manim import *

class Tran(Scene):
    def construct(self):
        A = Tex("A")
        B = Tex("B")
        self.play((A, B))

You are missing any form of animation command inside the self.play()

[yang-tsao]

Sorry, the code should be the following one:

from manim import *


class Tran(Scene):
    def construct(self):
        A = Tex("A")
        B = Tex("B")
        self.play(Transform(A, B))
