hi,<br>iam looking at improving scroll perf on webkit gtk port and came across this patch <a href="https://bugs.webkit.org/show_bug.cgi?id=15070">https://bugs.webkit.org/show_bug.cgi?id=15070</a> that uses double buffer.<br>
<br>Taking the patch only vertical scroll down seems to work. i was suspecting -ve values in gdk_draw_drawable scrollStore when dx/dy is <0, but that did not help.. <br><br>Also is there a way to capture the backing store data to an image (similar to cairo write to png). could not find one.<br>
<br>Appreciate any inputs on this. <br><br>thanks,<br>Zaheer<br> <br>
