Lag on iOS devices the first time the speed dial is opened

[MaelSemler]

Hello,
I was wondering if I was the only one experiencing a lag in the animation when I open the speed dial for the first time on iOS devices. It does not happen on Android. It is a simple speed dial used for the floating action button.

Anybody got this same issue and fixed it?

Thank you

I've encountered a similar problem, but it's on a Windows system.
