** Description changed: Description: Ubuntu Focal Fossa (development branch) Release: 20.04 Bug Detail: Mutter behave differently with Qt Application with Frame-less flags. - example: 1- they are not resizable. - 2- window snapping doesn't work. - 3- they cannot be moved around the screen like other apps. + example: 1- they are not resizable. + 2- window snapping doesn't work. + 3- they cannot be moved around the screen like other apps. Steps to reproduce: 1- Run any Qt frame-less window app (Qt::FrameLessWindowHint). (snap install olivia or snap install wonderwall, these are few apps which uses frame-less window hint optionally). You can build your own app with Qt if you have code. 2- Try to resize it. 3- Try to snap it to the edges. 4- Try to move it around the screen and try to move it long along X and Y axis. Expected Behavior: - 1- Qt::FrameLessWindowHint windows are supposed to be resized if they - are not set to be remain FixSize. + 1- Qt::FrameLessWindowHint windows with Qt::Window/Widget/Dialog flag + are supposed to be resized if they are not set to be remain FixSize. - 2- Qt::FrameLessWindowHint windows are supposed to trigger snapping on - window snapping gesture by user. + 2- Qt::FrameLessWindowHint windows with Qt::Window/Widget/Dialog are + supposed to trigger snapping on window snapping gesture by user. - 3- Qt::FrameLessWindowHint windows are supposed to move all the way - along the X and Y axis of user's screen. + 3- Qt::FrameLessWindowHint windows with Qt::Window/Widget/Dialog are + supposed to move all the way along the X and Y axis of user's screen. Note: Qt::FrameLessWindowHint enabled apps act normal under Unity7's Compiz/Metacity, KWin of KDE and xfwm of XFCE.
