We are evaluating qtwebkit based browser application on iMX6 Solo. Just I would like to know how webkit utilizes GPU? We have already evaluated qtwebengine and we found significant difference in performance (FPS) when we reduced GPU clock. In case of webkit, we could not able to find any difference in FPS when we reduced GPU clock (observed same FPS with original clock and reduced clock). So we are trying to understand how webkit utilizes GPU as compared to webengine?
