iTerm insert control sequences on switching to another app and back

• iTerm2 3.0.8:
• 10.11.6
• com.googlecode.iterm2.plist;
• debuglog.txt

Detailed steps to reproduce the problem:

1. open a ssh session with tmux in it;
2. kill the connection (no the client);
3. wait till ssh client exits with error (broken pipe);
4. open cat;
5. switch to another app and back

What happened: ^[[O^[[I appeared in terminal

What should have happened: nothing

Just found out that the problem doesn't occur with ssh session to another machine. The difference between them is tmux version: 1.8 on the machine to which died connection cause the problem and 1.5 on the other one.

tmux turns on focus notifications. If ssh dies, this gets left on. You can turn off Prefs > Advanced > Apps may turn on Focus Reporting to prevent this.

I should detect when focus reporting goes awry and notify/turn it off.

Milestone changed to %Feature Complete 3.1

Yep, changing the setting you've suggested helped.

Fixed in commit 0fd7cfd6.
