I see what you mean.
I suppose it is a side-effect of requesting the freetype back end rather
than the win32 back end.

The window size in your screenshot is the same as I see under linux.
The difference is the vertical space allocated for each text string.
The program is reserving too much space for each line of text, presumably 
because  pango_layout_get_extents() is reporting too large a vertical extent.
I am guessing that it is another bug in the Windows implementation of pango.
