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 with Qt::Window/Widget/Dialog flag are supposed to be resized if they are not set to be remain FixSize. 2- Qt::FrameLessWindowHint windows with Qt::Window/Widget/Dialog are supposed to trigger snapping on window snapping gesture by user. 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.
