the table is not correctly drawn on the right by example

On several websites, the background-image css property is not correctly renderered. Indeed it is rendered with a shift.
Here is a list of websites:

Seems to be related to the QPainter.
This bug does not appear in QT/X11 port.

Test case : http://joliespages.com with only the header in order to simplify the web site.

Test case: install this index.html plus his pictures associated and try to run webkit/qws/directfb

The centered image should be shifted from the left and right as described in the first attached screenshot.
