Button text vanishes for a couple seconds...
So I have a simple Tablet prototype with some Bootstrap UI controls.
One numeric input field and 2 primary buttons under it.
When the input field has focus the number keyboard pops up and just covers the 2 buttons.
When I click outside of the input field ad the keyboard retracts, the first button is fine but the text of the second button is missing for about 2 seconds then it appears with a kind of fade in effect.
Anyone have any idea what's going on and how to make the button text just stay on both buttons?
