Here's the text from the Emacs PROBLEMS file: *** In Shell buffers using ksh, resizing a window inserts random characters. The characters come from the PS2 prompt, but they are not followed by a newline, which messes up the next command you type. This strange effect is caused by Emacs 25 and later telling the shell that its screen size changed. To work around the problem, customize the option 'window-adjust-process-window-size-function' to "Do not adjust process window sizes" (Lisp value 'ignore'). regards, mike
