Pixijs slows down in google chrome, what is the reason?

Question

JavaScript

Tell me what is the reason for the brakes. In opera, mozilla, yandex, even in IE everything works fine 60fps, but in chrome 20ftp. Here are 3 demos from the official pixijs website:

This part of pixi is of interest , since you need to work with animation in json format, from the spine. If you know how this problem is solved, tell me, or tell me how you work with such an animation.
