I will suggest you several ways to solve shape instability: You can increase the collision margin: Set a larger collision margin for your shapes. The collision margin is an invisible padding around the shape that helps to stabilize contacts between objects. Adjust the shape's mass subway surfers and...

Optionally, you can install the compiled Bullet library on your Ubuntu machine or the Raspberry Pi. This step is not necessary if you plan to directly link to the library during your engine's compilation.

Instead of moving the kinematic object abruptly from -5.f to 1.f, consider implementing a smooth transition over multiple frames. This can help reduce the sudden force applied to the dynamic object and minimize undesired behavior.

Regarding the X/Y ratio threshold, it's possible that the tall box's tipping behavior is influenced by friction at the contacts. To investigate this, you can try setting the friction values to zero for both the floor and the dynamic object. This can help determine if the transition between behaviors...

I watched the video, thanks for your help.
