I experienced a similar problem generating PNGs on linux and found
that installing a missing font library corrected the situation.
Hope this helps,

The weird thing is that it does not generate an error. It does
generate a
file with a figure of the correct size, but the figures are mostly
just
white space, or small parts of the actual figure.
X11 is not installed on the machine so I have to use type="cairo".
I have
tried installing and updating cairo, glib2, gtk+ in linux, and
installed the
R-package "Cairo", but with no result.
