How to remove jerky when loading data in Angular?

Question

Angular

Hello.
Now the data is loaded via the API using a promise, and this is already causing a jerk. How to avoid? So that everything is smooth, so far interactive with the 3rd group of disability, it doesn’t occur to me how to deprive him of it (due to CSS animation, at least some smoothness was achieved, but this is not enough, it’s clear that it’s a crutch)
Thank you, good luck to everyone work flow
