Device frames don't load immediately

[agordeev]

Insteat, they blink in after a small delay. Also, when the page is not active for some time, the same effect occurs.
Browser: Firefox 50.1.0.

Hey andrew8712,

I think thats caused by the lazy loading. We do not perload every device when the site loads. We would end up with a lot of traffic. Insted when you change the phone, the browser loads the image. You can test this by switching the same 2 devices. On the first switch, the delay occurs. From the second time on, the devices switch intant.
