Grid shows scrollbar when width is set to 100% (IE 10)

Browser: IE10
SmartGwt version : 3.1p

Grid (listgrid, treegrid) shows horizontal scrollbar when width is set to 100%

I have added the html5 doctype and do not have any third party css.

Sample code:
VLayout vPanel = new VLayout();
vPanel.setWidth(400);
vPanel.setHeight(500);
vPanel.setBorder("1px solid red");

ListGrid grid = new ListGrid();
grid.setWidth100();
grid.setHeight100();
vPanel.addMember(grid);

Does not happen in IE9/FF.

Please let me know if there is a fix/workaround for this issue?
