Since Ubuntu 18.10 I’m experiencing a weird bug on Terminator, the terminal I use because of its broadcasting functionality.
The bug is known and tracked on launchpad but not fixed ¯\_(ツ)_/¯ so I found a quick way to fix it (tested up to 20.04), enjoy!
sudo mv /usr/bin/terminator /usr/bin/terminator.SAVE
cat <<TERMINATOR > /tmp/terminator
#!/bin/bash
sh -c "DBUS_SESSION_BUS_ADDRESS='' /usr/share/terminator/terminator"
TERMINATOR
chmod 755 /tmp/terminator
sudo mv /tmp/terminator /usr/bin
