But setVisibleContentsRect expects a rectangle describing the page content area that is actually seen, and that should include the page scale factor. Also, the area should not be beyond the page contents boundaries. 893015 1 202737 marcelo.lira 2013-05-23 12:59:53 -0700 Created attachment 202737 Patch 893233 2 202737 noam 2013-05-24 02:12:43 -0700 Comment on attachment 202737 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=202737&action=review > Source/WebKit2/ChangeLog:3 > + [WK2] Misuse of DrawingAreaProxy::setVisibleContentsRect() in WebView::updateViewportSize() You should update this to reflect the new bug title. > Source/WebKit2/ChangeLog:10 > + Visible contents area passed to DrawingAreaProxy::setVisibleContentsRect() > + must include page scale factor and avoid crossing the contents > + boundaries.
