I don' know if it will resolve this particular issue, but QItemDelegate was superseded by QStyledItemDelegate for exactly that reason. I would suggest trying that instead.

QMacStyle and QWindowsStyle doesn't have such "fancy" selection and i need to draw selection manually (filling text rect with QPalette::Highlight color).
