Selectable QTableWidgetItems are not drawn correctly when scrolling the table widget. The attached example shows this. The items from 0 to 10 are initially unchecked and items from 11 to 20 are checked. When scrolling the table some of the unchecked items become checked and vice versa.

This is only reproducible with windowsvista style. With, for example, windowsxp style the items are drawn correctly.

This worked correctly with Qt 4.8.4.
