When I resize the width of a treeview with some text within to be narrower, then if the text is truncated, it "jumps" to 1 pixel above.

For example, open examples/itemviews/simpletreemodel
When you stretch the window, if a line is fully displayed, it will be lower by 1 pixel.

This is a regression, it worked on Qt 4.6.0
Apparently it works too with an old revision of Qt 4.7 from two weeks ago (before Easter).
