<pre>There is a bug in Cairo DirectFB backend. After applying the patch from the
link below to cairo-1.12.14
<a href="http://cgit.freedesktop.org/cairo/commit/?id=631bf299256e11a17511977f357e0353fb5615f7">http://cgit.freedesktop.org/cairo/commit/?id=631bf299256e11a17511977f357e0353fb5615f7</a>
The directfb surface is locked in _cairo_dfb_surface_map_to_image() but not
unlocked in _cairo_dfb_surface_unmap_image(). Therefore, it is preventing the
application from using that directfb surface, such as surface->flip.</pre>
