Canvas Renderer event

Hey there,

in my game i have a canvas with a orthographic camera on it.

In this canvas i have some placeholders for "Text", like player names, attributes etc. Moreover there is a "CanvasController.cs" attached to the canvas.

When scene is loaded, i use the "Start" method of the "CanvasController.cs" to set all text.

BUT: this is what happens:

Scene loades correctly => Text is set after 1-2 seconds !? => During this period of time, i cant click any buttons on canvas

So, why is the canvas taking so long? Is there any "canvas finished rendering" event i can register to?

Thanks and Greetings!
