70-second freeze on tmux attach/detach
- iTerm2 version: 3.3.2
- OS version: High Sierra 10.13.6
- Attach ~/Library/Preferences/com.googlecode.iterm2.plist here (drag-drop from finder into this window): com.googlecode.iterm2.plist
- Attach a debug log, if possible: the debug log is ~67MB, which is too large for gitlab
- Are you reporting a performance issue, excessive CPU usage, or a hang? Please attach a sample: Sample_of_iTerm2.txt
Detailed steps to reproduce the problem:
- Get iTerm2 into some odd state
- Run
tmux a
, or press ctrl-b d if you're already attached to a tmux - Beachball!
What happened:
iTerm2 freezes for 70 seconds at 100% CPU usage when I attach or detach from this tmux. Using tmux -CC a
doesn't freeze, bizarrely.
What should have happened: iTerm2 shouldn't freeze and hog the CPU for a full minute.
