Created attachment 192489 [details] Simple test case I've tested this patch on WebKit Clutter with the attached page, and it looks like the transition is happening twice - once because of the CSS transition that is defined, and one because when WebCore sets the final result in the layer, the clutter transition is still set on the actor, so it happens again. I'm getting this warning, as well: (MxLauncher:24704): Clutter-CRITICAL **: clutter_timeline_set_progress_mode: assertion `mode < CLUTTER_ANIMATION_LAST' failed

(In reply to comment #3) Thanks for the review! > Created an attachment (id=192489) [details] > Simple test case > > I've tested this patch on WebKit Clutter with the attached page, and it looks like the transition is happening twice - once because of the CSS transition that is defined, and one because when WebCore sets the final result in the layer, the clutter transition is still set on the actor, so it happens again. Yeah, it's a known issue and dealt in bug110607. Please see bug110607, I applied it to webkit-clutter as well. I'm getting this warning, as well: > > (MxLauncher:24704): Clutter-CRITICAL **: clutter_timeline_set_progress_mode: assertion `mode < CLUTTER_ANIMATION_LAST' failed This is because webkit-clutter is using different toClutterAnimationMode in PlatformClutterAnimation.cpp. webkit-clutter's one is a little old so I think we need to replace it with the one of WebKitGTK+. You may want to refer https://developer.gnome.org/clutter/stable/ClutterAlpha.html#clutter-alpha-register-func And actually I think we don't need to care about timing functions anymore because clutter starts to supports them for css3 transitions since its version 1.12. https://developer.gnome.org/clutter/stable/ClutterTimeline.html#ClutterAnimationMode
