Use pango_cairo_layout_path() instead of pango_cairo_show_layout(). - pango_cairo_show_layout() will stroke and fill text. - We want shape itself add pathes to cairo context, but not stroke and fill. - redraw manager will apply paints (source surface) on cairo context before stroke and fill to get right color. - Using pango_cairo_show_layout() we can not apply stroke and fill color seperately. So, pango_cairo_layout_path() is used instead of.
