Yes. I am on GNOME Terminal 3.20 on Ubuntu 17.04. I have also experienced the problem on xfce4-terminal on archlinux. Furthermore, a friend I talked to mentioned they have the same problem, on their macbook-pro, although I'm not sure of their terminal

I'm not sure what you mean. When i type echo $TERM, i get xterm-256color. Some more detail is that this graphical glitch also happens sometimes when i search, and i think there are some answered questions about that issue so I will try out those solutions.

My term is 'xterm-256color'

Thank you very much. Since I'm new to emacs, could you explain how I can use that function in emacs? I think I have to add something like add-hook in my .emacs.el file?, but I don't really know how to do that.
