https://bugs.webkit.org/show_bug.cgi?id=25696#c2 thanks to paul for the guidance and for the leading work / patches on which this is based, paul, the code that you sent me has a bug where the scrollbars on a frame will go "blank" and disappear when you move the mouse over them. the reason is that the empty rect causes the return out of the paint function, prematurely, i fixed this by allowing the scrollbars always to be painted. if anyone can think of a better way to do this other than to comment out code (even though it can be demonstrated as completely broken) that'd be great. testing this i used http://pyjs.org/showcase/Showcase.html then click on "Frame" (left-hand-side) and then shrink the browser window to 800 pixels to get a horizontal scrollbar in the frame as well. with the patch from the above link, everything's fine. paul, chris, your help was _really_ appreciated. the client will be well-'appy. l. -- View this message in context: http://www.nabble.com/WebKit-partial-rendering-issue-tp20721190p23564079.htm...
