Hi Philippe, We have fixed a whole bunch of macOS specific bugs with enter/leave/hover logic, and also with the handling of window modality on macOS; e.g. https://bugreports.qt.io/browse/QTBUG-36926 https://bugreports.qt.io/browse/QTBUG-78970 https://bugreports.qt.io/browse/QTBUG-92040 Perhaps those are the issues you have been running into as well? There might be more, in which case it would be good to have specific bug reports.
