When I'm SSH'd into any other server with Terminal..
Text will start display over hidden text, when I search through history, text will only show fragments. When I start typing, letters will appear within those fragments. Or characters will appear that are phantoms, and as I type, the letters I'm writing will overwrite them.
I only customized small things like fonts and colors in Terminal.
This has existed in Mac Terminal for at least five years of me using them. Why does this happen and what can I do against it?
