I am new to Godot Engine and I have been experimenting quite a lot with it. I have made a simple test project. I am spawning/adding child to the world scene of both 2D kinematic body and 2D Rigidbody simultaneously. After sometime, microfreezes/ stuttering occurs when run in editor . The same can be seen even after exporting it to android.
The test project is here
I have Windows 10 Pro.
