I am using NetBeans 12.5 another way to replicate this bug: add two JFrame and configure a button in one of the JFrame with the following code:
new NewJFrame().setVisible(true); this.dispose(); Wayland session: the OS freezes and closes the session. Xorg session : the OS freezes but it does not close the session and keeps the program open -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2016308 Title: gnome-shell crashed with signal 6: libmutter:ERROR:../src/core/window.c:1533:meta_window_unmanage: assertion failed: (window->display->focus_window != window) To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2016308/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
