Created attachment 93367 [details] Test case I was loading the attached page on Chromium Linux (WebKit r86394) and noticed some scrolling oddities when scrolling all the way to the left. In some cases, it appears as though the page doesn't scroll all the way that it should and cuts off some of the text. If I mouse down and drag left, the page scrolls the rest of the way. This happens intermittently but seems to happen more if I am scrolling slowly.
Created attachment 93368 [details] Incorrect scroll screenshot I'd expect to see ZYX all on screen unlike this screenshot.
Created attachment 100669 [details] Another bug. The content is painted in wrong place after resizing the window. (not 100% reproducible).
Created attachment 100670 [details] Qt porting has the same problem.
Created attachment 101154 [details] Not only RTL pages have this bug, all scrollable areas have this bug. This test case shows how to 100% reproduce this scroll position bug.
