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?

I have uploaded mintty 2.7.4 with the following changes:
Since about November/December last year I'm having problems with screen
and tmux sessions in mintty not correctly refreshing and leaving garbage
characters displayed in the terminal. It seems that the terminal size
is not always correctly reported, especially if you make the window
occupy the left or right half of the screen via Windows shortcut.
This might be related to some issue with terminal geometry as perceived
by the shell (see
Have you checked that? Recently changed your prompt? Try with basic
prompt (PS1="\w> ") please.
Additionally, there seems to be an off-by-one bug when the last line of
the terminal needs to be scrolled up in order to show content that is
longer than the remaining width. This happens when you for instance
recall a long command from history. It's hard to see what exactoly
happens, but it looks like the one character too many gets printed (and
wraps onto the next line) before the whole terminal window gest scrolled
up and the rest of the command gets printed in the line below the
single wrapped character. That remainder is in various states of
disarray, showing both remnants from the original prompt on the last
line (now three lines up), empty /spaces where there should have been
characters from the command and then of course parts of the command.
