    Env: Ubuntu 14.04LTS
    Gtk:
    lvtk-gtkui-1 lvtk-gtkui - LV2 Toolkit GtkUI
    gtkmm-2.4 gtkmm - C++ binding for the GTK+ toolkit
    gtk+-unix-print-2.0 GTK+ - GTK+ Unix print support
    gtk+-2.0 GTK+ - GTK+ Graphical UI Library (x11 target)
    gtk+-x11-2.0 GTK+ - GTK+ Graphical UI Library (x11 target)
    Qt: Qt5.9.2

    Reproduce:

    1. build example : recipebrowser
    2. run recipebrowser.
    3. Rapidly drog the mainwindow frame, so that the mainwindow do resize rapidly.

    Test result: Program received signal SIGSEGV, Segmentation fault.
    Backtrack:
    Program received signal SIGSEGV, Segmentation fault.

      Thanks for the message. Can't reproduce it with Qt 5.10 on up-to-date desktop Linux. Note that this is a forum for users helping each other. It's very unlikely that a Qt framework developer will read this thread. But you can file a bug report at https://bugreports.qt.io.

        Hi and welcome to devnet,

        You should first update your version of Qt. If you have to stay with 5.9 then try 5.9.3 and if not then 5.10 since it just got released.
