After moving the Hierarchy to the bottom of the screen I found that the canvas seems to have changed height and size. Plus the items I added to the canvas were now off centre and too small because of this?
The canvas is set to Screen Space Overlay, so how do I avoid this issue.
Unity Version: 2019.2.0b6
Screen Space Overlay means that your canvas will be the same dimensions as the game screen. So if you change the size of your game window, the canvas changes to match it. This is so you can build your UI to support as many aspect ratios and resolutions as possible, using your game window as a preview of potential device screens.
