I was having the same issue. After opening appearance-preferences, the cpu usage spiked to 100% and I could not select/click on anything in the window except to close the applet. Also got this
(gnome-appearance-properties:13667): Gtk-CRITICAL **: gtk_widget_map: assertion `GTK_WIDGET_VISIBLE (widget)' failed (gnome-appearance-properties:13667): Gtk-CRITICAL **: gtk_widget_map: assertion `GTK_WIDGET_VISIBLE (widget)' failed As given in this and bug#138726, I had gtk-qt-engine installed. Removing it seems to have solved the issue. -- Gnome-appearance-properties freeze https://bugs.launchpad.net/bugs/145827 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
