I have a tmux session inside Putty. It was fine for past many months, but now I see a strange thing. When I maximize a normal Putty window, and if cursor is not on a new line, then I get some weird ANSI Sequences in the shell. Eg, I maximized 4 times to get:0;44;8m  0;46;8m  0;50;8m  0;55;9mIt happens only on maximize, not on restore.If cursor is on a new line, then the codes printed start with ^[[<, & then the ANSI Sequences. Eg, when I maximised 4 times, ensure that the cursor is on a new line, I got:^[[<0;64;8m  ^[[<0;138;8m  ^[[<0;95;8m  ^[[<0;79;7mWhat is happening ?I restarted the session and issue is not happening now. How to debug next time it happens ?
