Short description of error
On MacOS Mojave in Blender (both 2.80 and 2.81 2019-9-16) when I click view animation, animations only take up the lower left quarter of the window (see screenshot). Even when resizing the window it stays this way.
Exact steps for others to reproduce the error
With any file: click Render -> View animation
