issue using both add_fixed_in_frame_mobjects and TransformMatchingTex

[quentinplsrd]

I have an issue when displaying a LaTeX equation in a ThreeDScene using add_fixed_in_frame_mobjects , and then trying to update the equation with TransformMatchingTex.

The initial equation displays perfectly, but there is a glitch when updating the equation.
The updated equation is first displayed on the (x,y) plane of the 3d scene, then disappear, then correctly displays on the frame like it should, but without the smooth transformation expected by TransformMatchingTex

        self.add_fixed_in_frame_mobjects(eq3.shift(DOWN*3.3))
        self.play(Write(eq3))
        self.wait()
        self.add_fixed_in_frame_mobjects(eq4.shift(DOWN*3.3))
        self.play(TransformMatchingTex(eq3,eq4))
        self.wait()

Is it a known issue, or am I doing this incorrectly?

Thanks

"issues" are meant to report bugs in the code base, not questions about your own code.

I'd suggest that you come over to the Discord server - there have been several previous discussions and solutions on these topics.
