I am not familiar with cairo on Windows, but on the cairo mailing list there recently was a posting that claims that cairo wont support an alpha chanel on Windows directly. You will have to use cairo_win32_surface_create_with_dib() to get full alpha support for your surface.
This could well explain the second issue you are facing.

The are a number of issues:

1. backend does not default to a known font if the "default" font (Helvetica) is not found (easy workaround is to set the default font to a known font).

2. Images are not displayed.

3. After a window redraw or two, the window turns black and you get the error message "Cairo status 'out of memory' in copy'"

See screenshots for more info.
