# Check for interactive shell
# Terminal is the default for many cases, even for SFTP!!
# So in order for everything to work, for example SFTP,
# we need to check first that the terminal is interactive,
# meaning, that we are in a for-user shell.
if [[ $- == *i* ]]; then # Check for interactive shell
  
  if [ -z "$TMUX" ]; then # Not inside tmux
    session_name="$(whoami)_$(date '+%Y-%m-%d %H-%M-%S')" # Generate a unique session name

  else # already inside tmux
    nn
  fi

I access the terminal through:

• Windows
• V.Code terminal
• V.Code SSH

And then tmux opens, and NNN.

When it happened, I could reproduce it, with the steps presented below. Then I tried to kill tmux and go bare terminal,
and it stopped happening even with tmux... really, I don't know how to reproduce it right now.
I could before 5 minutes with the steps below.

Exact steps to reproduce the issue

Open a terminal with Ctrl-~ in VCode:

Drag the terminal up to make it as editor (therefor resizing the terminal) :

Everything seems okay so far..

Open help (Shift /) :

Woah! ... something died..

Close help:

wow ... all those quota.user? They definately don't exist

This is me moving the cursor (arrow keys down) to the entry below "bin":

which is as we see (multiple times) "boot"

This is me moving the cursor (arrow key down) to the entry below "boot":

which is as we see (multiple times) "dev" (not "devta.user")

Ant this is the result after moving the cursor a lot (up / down arrows)

I tried redrawing the screen in tmux multiple times, no luck
(refresh-client -l) (C-b r)
and I even tried the ^L of NNN (Ctrl Shift l / Ctrl l / Shift L)
and nothing changed.

After resizing the VCode window (and therefore I guess resize is being propagated) it seems like it's fixed...
But I can easily see the problem persists, by typing / to filter, and typing an (existing) letter... Everything get's corrupted again...

I will install the latest NNN and try it there too.
Although now that I can not persistently recreate it, I might take a week to provide more info.
Don't worry though, it's happening at least once a week, the past 3-4 months or so for sure.

It would be nice to have a config option, to skip smart redrawing, and force it to full redraw..
I am thinking to myself, rather than having some performance boost, we are on a Web server machine, I think it can handle full redraws, but the buuug.... it's not okay.

Thanks for this MAGNIFICENT program, it's one of the BEST I have ever seen :D

Thank you for the kind words and sorry for such a late response. When this was originally posted I tried to recreated, but I couldn't. I was hoping someone else would take it on, but that obviously wasn't the case.

Do you still experience this issue? Can you reliably reproduce it?

[KlzXS]

Closing as there is no response and no one was able to reproduce.

Ehhhmm... sorry for the late response myself too.
I saw this like a week before, but I just got the time to answer (vaccations).

I really thought my answer would be "Yeah! Of course I can reproduce, how do I help you?",
but it seems the problem has gone away (? O,o .... xD)
Right now, even after NNN has openned, in VCode, with tmux, and I have for example traversed to a folder,
I can simply resize the window, and NNN works like NOTHING HAS HAPPENED!! OMG I'M HAPPY!! XD haha.
It seems to work PERFECTLY fine!

From the time I opened this issue, I think remember:

• Updating Visual Code
• Updating NNN
  (Though I did not update tmux)

So, maybe it was something with those two.
If anyone finds this issue has the same problem,
try those too actions.

And, I guess, sorry for your time, it seems like updating the programs fixed it.
