I have a TextureRect (called Canvas) which the user can draw inside of with the mouse. On top of that there is a UI button layer they can interact with.
Problem is I'd like all the UI elements to be inside their own control node so I can show/hide them easily. However when I tried this using a Full Rect control I was no longer able to draw inside the Canvas layer.
If I set them inside a top left anchored control it works fine. But this messes up the position of some of the UI elements
