Using Stylesheets on a scrollpane (or on any parent widget) results in graphics problem in the initially not visible area. See attached screenshots for the effect this produces. It seems that the background in this area is not cleared. The contents of the stylesheet or what widgets style it changes does not seem to affect this.

If I remove the stylesheet from the scrollarea and move it to the individual widgets the problem does not surface.

This happens for me on 4.6.3 and 4.6.2 with Nokia Qt SDK beta, Qt Creator and Carbide.c++ when using S60 5th Edition SDK. I have not tried on S60 3rd Edition.
