Masking layer doesn't work well. A test case is here, "Slide in" in http://www.apple.com/html5/showcase/transitions/

Comment on attachment 196795 [details] Patch In the current implementation we do clipping at paint time, apparently because we need to take the scroll offset into consideration for the clipping, does this change work when a layer has masksToBounds and is scrolled?

Would you let me know any sample for the case concerned? :)

In webkit-clutter we do the clipping at paint time, I am not 100% on why, but I remember Joone explaining at some point. Merging this patch in webkit-clutter (which moved the clipping from paint time to setMasksToBounds time) broke the drawing of layers in pages such as this one: http://www.anthonycalzadilla.com/css3-ATAT/ I am still building webkit-gtk with clutter AC to test if that also happened in webkitgtk's case.

Actually, this page is a better test, zooming and scrolling around should show the issue: https://developers.google.com/maps/documentation/javascript/examples/map-simple?hl=pt-br
