Map is not fully displayed in non-widescreen resolutions

Map (item) doesn't fit the 4:3 aspect ratio screen resolution when using off-hand.

What I expected to happen was...:
Be able to see all the map

What actually happened was...:
Part of the map doesn't fit screen

Steps to Reproduce:

2. Take the map in the second hand.
