In Safari, if you have "new tabs open with empty page" and "show compositing borders" on, opening a new window will result in white repaint counters on the tiles, indicating that accelerated drawing is not being used for the tiles. Subsequent navigations will do the right thing. This regressed in kling's http://trac.webkit.org/changeset/154616 -- I'm guessing the part in WebPage.cpp where the DrawingArea construction was reordered, but could be something else.
