For that i compiled cairo-x11 with xlib-xrender enabled. But when i run any application that uses cairo the fonts are not rendered properly and some black boxes are overlapping the some characters of the string and some extra lines are coming behind some characters (as shown in the attached screenshot of gtkperf application that uses cairo with xlib-xreneder option enabled). But if i compile cairo by disabling xlib-xreneder the display is good and fonts are displayed properly, but the time taken for rendering is increasing two times. I think as xrender takes advantage of acceleration available in tinyx/x11 it is speeding up the rendering. But i didnt make any changes in either xrender code or cairo code. <br> <br>Can anyone identify the reason for this improper display if we enable xlib-xrender option in cairo. Is it a bug in cairo/xrender implementation or we are missing some thing else in the configuration?? The configuration settings we are using is mentioned below.<br> <br>we are using cairo-1.8.0, gtk+-2.12.3, pango-1.22.1, fontconfig-2.6.0, freetype-2.3.7, pixman-0.12.0 and tinyx server xorg-server-1.5.1 (R7.4 release) and arm-v7 toolchain used for cross compilation.<br>cairo configuration settings:<br> ./configure --enable-xlib --enable-xlib-xrender --disable-pdf --disable-ps --disable-svg --enable-png=yes --with-x --disable-some-floating-point<br><br>Waiting for ur valuable reply....<br></div></div></div></div><p>Muthukumar</p> <p> </p><p> </p><p> </p><p> </p><p> </p><p> </p><p> </p></x-BODY><p> </p><p> </p><p> </p><p> </p></x-BODY><p> </p><p> </p><p> </p><p> </p></BODY></HTML>
