Window is too tall and is not resizable

[vi]

Steps to reproduce:

1. cd git.git
2. git-age git-svn.perl

What happens:
I see top part git-age window with partial text and top part of authors list. The full window is visible only when I do "xrandr ... --scale 1x3" and it is not resizeable.

What should happen:
Normal sized window is displayed with all necessary scrollbars. It is resizeable and I can move sliders to extend or shrink authors or bottom panel.
