Issue 3477 - iterm2 - Cursor Invisible in emacs under tmux ...

I found this issue on google, but does not exists anymore and didn't find anything on gitlab.

Since I upgraded to tmux2.0, the cursor on emacs (24.5) is invisible. It works fine under osx Terminal.app though.

Issue is also present w/Emacs 24.4.1 in iTerm2 2.1 under tmux.

It's related to tmux 2.0 release, but I'm not exactly sure what has caused this problem. There seems to be more bugs introduced by tmux 2.0 than expected.

EDIT: typo.

Might be a tmux thing, but Terminall.app supports it as expected and I got lost trying to submit a ticket to the tmux tracker.

I can verify that the cursor appears in iTerm2 2.1 using emacs 24.5 but doesn't when running Emacs under TMUX.

Can someone who has this issue please provide a shell log? Do this:

1. Shell>log>start
2. Start tmux, start emacs, do whatever it takes to make the cursor is disappeared
3. While the cursor is not visible, do Shell>Log>Stop
4. Attach the log to this issue.

Never mind, I see the issue. There's a compound DECSET. Not hard to fix.

Milestone changed to 2.1.1

Status changed to closed

Fixed in commit 0decc17a

I've been looking for a good bug to justify a new dot release and this is it. I'll push out 2.1.1 hopefully today.

Awesome, I can verify that it's no longer an issue for 2.1.1.

Same here. Thanks!

I'm running iTerm2 2.1.1 and still see the problem when tmux is nested. In my case, I run tmux locally, and within tmux, I ssh to a remote machine, run tmux on that machine, and run emacs, the cursor goes away. If I do NOT run tmux locally, ssh to the remote machine, run tmux on that machine, and run emacs, I still see the cursor.

@bstiles Hm, I get the same in Terminal. I think you have found a bug in tmux.

@gnachman You are right. I had tested Terminal when I was trying to figure out what was going on, but didn't circle back to test the tmux in tmux case. Thanks.
