I have set a nearly fullscreen size UI in game, and added a component "Loading panel" in the root of UI perfab, then uncheck the "visible on awake".
But when i click the start button of title, my UI is showing and hidding in a very short time.
I think maybe the nani is control UI by canvas group. After tracking the alpha of it, i found this value in beginning is 0, but when i start game,it suddenly jump from 0 to 1 and plunge back into 0. i'm not sure it is the reason why my UI flashed once, because it happened in all of defaultUI i tracked , but only my UI flashed.
How can i fix that?
