Proposing a fix to the flickering CSS animations, by displaying the last frame until the WebProcess sends other commands to update it. My approach is different from the behavior before (shown the unfiltered layer data), and the current one as well (shows the last update sent by WebCore),

Created attachment 203046 [details] draft patch I tried to add a mechanism to disable animation fallbacks when the WebProcess generates an update. The mechanism seems working, but there is still flickering. Am I did something wrong?
