  * Scroll speed (causes dom manipulation in this example)

This is a known issue. On Mac, with Qt, the scroll() function does not blit the
pixels, it forces a full repaint of the view.

This is not a WebKit issue, and the developers of Qt are aware of the problem.
You can try to render the web page with OpenGL. OpenGL always do full update,
but the speed of rendering should compensate.


  * Window resizing
  * CSS resizable columns of from “resize: horizontal”

These are layouting problems. I did not know there was an issue on Mac, some
profiling will be needed.
