Model not render in safari IPhone

Bugs
10

In a somewhat fictional way, I managed to fix it in a simple manner, and I don’t know why, and I don’t understand either, but it worked perfectly.:

 const canvas = document.getElementById(domId) //Is canvas babylon render model
 const gl = canvas.getContext("webgl");
 gl.disable(10);

//.... initialization engine ....

 engine.disableUniformBuffers = true;
