Summary0036878: Resizing form by mouse doesn't always work in design time mode.
DescriptionWhen moving mouse cursor on bottom right or left corner border and pressing the left button of the mouse to resize the form, sometimes the IDE doesn't register this action and thus nothing happens. Only if doing same thing again, the IDE will register the action and resize the form correctly.

This bug only happens in design time mode; doing form resizing when application runs, it works.
Steps To Reproduce1. Try to grab either bottom right or left corner of the form and start resizing the form by moving the mouse around.
2. Observe either form resizing correctly or nothing happening.

Are you sure that Qt have problem ? I cannot reproduce it here .... Fedora 29 64bit, KDE Plasma. What's your window manager ?

OpenBox is the window manager, LXDE is the window desktop environment.

It will be nice if you can test with another environment (KDE,XFCE,Gnome) gtk2/qt/qt5

Something strange is going on during design time. It seems that IDE in design time mode adds its own area where window borders are.

Please observe attached animated .gif.

Hmm, looks like that area only appears when using QT widgeset. There is no visible visuals when using GTK2 widgeset, see attached animation.

DesignWidget is embedded as form inside form , so maybe that's what you see - double borders.
