Is this within tmux or after leaving tmux (see comment below)? It would 
be help to cross-test this; if it's mintty, which version would show the 
behaviour first? What happens in xterm?

This might be related to some issue with terminal geometry as perceived 
by the shell (see 
https://github.com/mintty/mintty/issues/377#issuecomment-137728631). 
Have you checked that? Recently changed your prompt? Try with basic 
prompt (PS1="\w> ") please.
