I have a Mate spin of Fedora 28. I hadn't used it for a while, but I don't recall seeing this problem originally (I may be wrong though.) When I'm typing in Gnome Terminal, (or anything else for that matter), my mouse pointer changes from the standard "insert text" cursor to something resembling cursive writing that I can't read. I've attached photos for reference.
If anyone can tell me how to disable this, I'd appreciate it.
