Performance drop on first time a UIButton is clicked in a scene

[alexh0101]

When my scene start and I press a UIButton for the first time, I get a 178ms lag.

In the Profiler, I see this:



But when I collapse the "UIButton.onClick", nothing appears with that 178ms.

Why is that happening?
If this is mandatory, is there a way to initialise whatever has to be initialised, while the scene is loading?

Try a deep profile to further narrow down the culprit. All UIButton.OnClick does is calls whatever delegate you've set.

Yeah, follow it deeper down. It's likely whatever you have set the game to do when you click. Say if you have a button "load new scene" then the stack trace will start at the UICamera, then to the button and further down until you get to the real culprit (loading a scene).
