Dear Lionel, I have tried recompiling the versions (only Cairo and Pango) as on this web page (<a href="https://wiki.mozilla.org/Mobile/DFBPorting#fontconfig">https://wiki.mozilla.org/Mobile/DFBPorting#fontconfig</a>), but it still shows corrupted text. I don't know whether its my ARM platform which only have this problem, or there are other problems with the newer version of DirectFB under ARM. Thanks very much and Best Regards William To <div class="gmail_quote">On Sun, Mar 14, 2010 at 2:21 AM, Lionel Landwerlin <<a href="mailto:llandwerlin@gmail.com">llandwerlin@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Le samedi 13 mars 2010 à 10:30 +0800, William To a écrit : <div class="im">> Dear Lionel, > > Can I know which version of Cairo and Pango you are using?

Using directly framebuffer pushes away the cache coherency problem... </blockquote></div>
