The graph view is rendered in the center of the screen so that it maximizes screen real estate.
Actual result
The graph is not rendered in the center of the screen, but is rendered to the top left of the screen and mostly cut off from view. This bug occurs when the Obsidian window is on my Macbook Pro 13", but does not on my external monitor (where it renders perfectly centered).
@wadesilvestro does this happen when you move the window from one screen do another?
Or you open the graph in one screen, and then you open again the graph in another screen?
