Description Nate Graham 2020-12-21 14:42:09 UTC 
https://invent.kde.org/plasma/kwin/-/commit/bf5155f82b1655a98311a73fa466484862f1cd09 causes KFind and Spectacle to no longer display minimize and maximize buttons in their titlebars. However they are still minimizble and maximizable using keyboard shortcuts, and maximizable by double-clicking the titlebar or dragging the window to the top edge of the screen
Comment 1 David Edmundson 2020-12-22 10:44:00 UTC 
xprop | grep _NET_WM_ALLOWED_ACTIONS 
_NET_WM_ALLOWED_ACTIONS(ATOM) = _NET_WM_ACTION_MOVE, _NET_WM_ACTION_RESIZE, _NET_WM_ACTION_SHADE, _NET_WM_ACTION_FULLSCREEN, _NET_WM_ACTION_CHANGE_DESKTOP, _NET_WM_ACTION_CLOSE

and clicking on spectacle.

So it's doing exactly what the client requested.


I checked why it's not set in spectacle. We inherit from qdialog, and that due to:

QWidgetPrivate::adjustFlags

    else if (type == Qt::Dialog || type == Qt::Sheet) {
        flags |= Qt::WindowTitleHint | Qt::WindowSystemMenuHint | Qt::WindowCloseButtonHint;

Because KWin now honors minimize/maximize button hint.
