Load the fixed-position manual test. Scroll to the bottom.
When I resize the window it doesn't set the right position and sometimes we even get position out of bounds (like use the fixed element test and scroll to bottom and then resize).
Adding Qt to the title. I see the same problem in Qt's MiniBrowser.
Swapping the order of translate and scale in EwkViewImpl::transformFromScene, EwkViewImpl::displayTimerFired and not scaling EwkViewImpl::m_pagePosition in PageViewportControllerClientEfl::setViewportPosition is fixing the issue for EFL.
The order of translate and scale was swapped in r136000.
I will upload a proper patch tomorrow, after better understanding the implications of this swap.
Resetting assignee. Kenneth is working on this.

This fixes it, but it would be nice to have it tested with Qt to make sure it doesn't affect pinch zooming etc.
Great! Qt runs well with this patch.
I tested in your scrolling test: http://www.dorothybrowser.com/test/webkitTest/css3/fixedelement.html
However, I can not test pinch zoom. I just resized qt window.
