I am getting this message very very frequently. Ubuntu 19.10
from the command line. The most intersting thing is that I may have 5 or 6 bash windows open. Aftetr executiong Meld from one terminal window. If I subsequently use meld from a Different teminal session, these errors spray-out on that first terminal's window: : 2020-03-18 11:52:47,201 CRITICAL Gtk: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed 2020-03-18 11:52:47,201 CRITICAL Gtk: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed 2020-03-18 11:52:47,201 CRITICAL Gtk: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed 2020-03-18 11:52:47,201 CRITICAL Gtk: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed I execute meld with the following command nohup meld "${@}" > /dev/null 2>&1 & Which sends output to dev/null. I am very surprised to see these messages coming on any screen since the output is sent to null. It looks to me like there's some kind of service involved not the actuall meld background process -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1712520 Title: [17.04][gnome] screen hanged after meld launched via terminal was put to sleep by C-z: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed To manage notifications about this bug go to: https://bugs.launchpad.net/gtk/+bug/1712520/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
