Describe the bug

I've been using yazi for like a month and it works very well, until today I upgrade it by yay -Syyu from 0.4.1 to 0.4.2 when I was using it with tmux sessions as usual. BTW it works well outside tmux.
Also tried building yazi from source(nightly version) and the issue remains.
Manually download the pre-released yazi 0.4.1 and unzip it, it back to work to me again.

Minimal reproducer

tmux   # create a new tmux session
yazi    # version 0.4.2

Anything else?

Checklist

• I tried the latest nightly build, and the issue is still reproducible
• I updated the debug information (yazi --debug) input box to the nightly that I tried
• I can reproduce it after disabling all custom configs/plugins (mv ~/.config/yazi ~/.config/yazi-backup)

@sxyazi if this is not reproducible to you then probably it's related to something else I upgraded today(something has conflicts with current yazi) since I was using yay -Syyu to update everything today. Then I think I'll stick with yazi==0.4.1 for now. Thanks!

[sxyazi]

I can't reproduce it. A more stable reproduction step is necessary, otherwise, it's really hard for me to make it doable.

Note that this is likely a tmux-specific issue, as tmux can interfere with the communication between Yazi and the actual terminal in various ways.

In your case, it's probably the terminal's response to Yazi's request that's getting messed up by tmux. So, you can first try to see if the issue exists outside of tmux. If not, then see if there's a way to consistently reproduce it within tmux.

@sxyazi it works well outside tmux. BTW what's the tmux version you are using? can you show me your yazi --debug so I can see if I could grab something useful from there? THanks

[sxyazi]

Sure, here you go
