Transforming Tex with opengl renderer results in "Exception: Could not find a ring to attach"
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()
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))
I am experiencing the same issue, except with ReplacementTransform(integer.copy(), hexInt). integer is an Integer() object while hexInt is a VGroup. The confusion is that it works half of the time and the other half it doesn't. This is the first Transform() and second self.play(). With the cairo renderer, it also works 100% of the time, no issues there.
