Lag when clicking SpeedDial for the first time after opening the app

[MikeJhoeB]

Firstly, the Speed ​​Dial is exactly what I needed for my application, thanks a lot, however I noticed that ALWAYS, the first time I click on the button to show the options, after opening the application, I feel a little lag to show the SpeedDialChilds. After clicking the first time, while I don't close the app, the next times I click on the button, I don't feel this lag until I close the app and open it again.

Is this a known issue? Is there a way to improve performance in the background until the user clicks the button? Thanks in advance, hugs from Brazil!

Note: I've tested it on 3 different devices so far, all of which have this situation
