When orientation switch happens, Qt gets first native event that StatusPane size has changed.
This causes updation of screensize in S60Data and fires Qt's resize event which re-draws all the widgets.
Unfortunately, style's background texture brush is not updated at this point, which causes this re-draw
to happen with invalid background brush (brush is still having previous screensize).

Study, if style could update the background brush immediately when new size is updated to S60Data.
