OpenGL - Githubissues

Description of bug / unexpected behavior

GTTR example rashes when using OpenGL with GUI.

Expected behavior

Work properly, perhaps at least without sound with GUI.

How to reproduce the issue

Code for reproducing the problem

```py from manim import * from manim_voiceover import VoiceoverScene from manim_voiceover.services.gtts import GTTSService class GTTSExample(VoiceoverScene): def construct(self): self.interactive_embed() self.set_speech_service(GTTSService(lang="en", tld="com")) circle = Circle() square = Square().shift(2 * RIGHT) with self.voiceover(text="This circle is drawn as I speak.") as tracker: self.play(Create(circle), run_time=tracker.duration) with self.voiceover(text="Let's shift it to the left 2 units.") as tracker: self.play(circle.animate.shift(2 * LEFT), run_time=tracker.duration) with self.voiceover(text="Now, let's transform it into a square.") as tracker: self.play(Transform(circle, square), run_time=tracker.duration) with self.voiceover(text="Thank you for watching."): self.play(Uncreate(circle)) self.wait() # Use GTTS with another language: class GTTSExampleVietnamese(VoiceoverScene): def construct(self): self.interactive_embed() # Set the lang argument to another language code. self.set_speech_service(GTTSService(lang="vi")) circle = Circle() square = Square().shift(2 * RIGHT) with self.voiceover(text="Vòng tròn này được vẽ khi tôi nói.") as tracker: self.play(Create(circle), run_time=tracker.duration) with self.voiceover(text="Hãy chuyển nó sang bên trái 2 đơn vị.") as tracker: self.play(circle.animate.shift(2 * LEFT), run_time=tracker.duration) with self.voiceover( text="Bây giờ hãy biến nó thành một hình vuông." ) as tracker: self.play(Transform(circle, square), run_time=tracker.duration) with self.voiceover(text="Cảm ơn vì đã xem."): self.play(Uncreate(circle)) self.wait() ```
