Describe the bug

Whenever I am editing files in vim - and I scroll down in the document the vim status bar in not properly redrawn and is messing up the UI. I have to hit "ctrl-L" to redraw every single time I scroll up or down in vim...

To Reproduce

1. Open a file with vim
2. make sure you have a status bar configured in your vimrc
3. scroll down in your document

Expected behavior

I should be able to use vim without having to manually redraw the screen whenever I scroll to a new section

Does this block you from using Warp daily?

Yes, this issue prevents me from using Warp daily.

Is this a Warp specific issue? (i.e. does it happen in Terminal, iTerm, Kitty, etc.)

Yes, this I confirmed this only happens in Warp, not other terminals.

Thanks for letting us know @michbsd We'll post any updates on this thread. Please :+1: and comment if you're also seeing this issue as it helps us gauge impact.

Hi @michbsd We weren't able to reproduce this with a simple status bar, would you be able to provide us with the .vimrc file you're using so we could try and reproduce this issue?

sure @dannyneira Here it is:

btw- it seems like it is only happening when I have ssh'ed to a remote host and running vim. running vim directly (locally) from my terminal is working fine.

[dannyneira]

Thanks for clarifying this is only an SSH issue, I was able to reproduce this in an SSH session with no changes to default vim. We'll investigate further and post any updates on this thread.

[dannyneira]

@michbsd It could possibly by one of the vim plugins you're using that's causing this issue. I used the same .vimrc file you provided without the plugins ( since I didn't have them installed ) in SSH and I wasn't seeing the same issue. I suggest you try and go thru commenting out the plugins until you find the culprit. Then, you can disable parts of your dotfiles just for Warp by using this conditional statement:

# Bash and Zsh
if [[ $TERM_PROGRAM != "WarpTerminal" ]]; then
# > What you want to disable here <
fi

[michbsd]

Thanks for your reply @dannyneira

Even when opening a default vim (without any configuration) and then just doing "set laststatus=2" the issue presents itself:

[dannyneira]

Thanks for confirming, I was able to repo this one briefly, but can't anymore so it appears intermittent on my end, I'll pass some steps along to the Eng team to see if they have any luck reproducing this. Appreciate your patience while we try and get to the bottom of this.

[michbsd]

Thanks @dannyneira - if it helps, I seem to be reliably reproducing the issue when ssh'ing to any FreeBSD machine.

[vorporeal]

@michbsd OOC - what version of vim are you running on those machines?

[michbsd]

@dannyneira

VIM - Vi IMproved 9.0 (2022 Jun 28, compiled Apr 11 2023 17:16:38)
Included patches: 1-1441
Compiled by root@124amd64-default-job-08
Huge version without GUI.  Features included (+) or not (-):

[michbsd]

Just confirming that this is still an issue with Warp v0.2023.05.09.08.03.stable_01

[ctipper]

+1 for this, using vi inside an SSH session is extremely unreliable and has caused me to lose data because I didn't know the shortcut to redraw the screen. I don't know about the status line, the whole view becomes corrupted.

Can confirm that this is using FreeBSD 13.2

[michbsd]

Still not resolved for neither.. I think it is a pretty basic use-case that one should be able to open vim in a remote session via terminal application. I am quite frankly surprised that the Warp team are working on fancy bells and whistles instead of fixing the very basics.

[ffd114]

Can confirm it still happen in v0.2024.03.12.08.02.stable_01 on MacOS, but on my linux machine it's working correctly

[michbsd]

@dannyneira can we get some eyeballs on this issue open for over a year now..

[dannyneira]

Hi @michbsd quick update, we're looking into this issue further and will post as we have them. Thanks for your patience folks!

[utsur0]

This is really hampering usage of Warp with pfSense and OPNsense boxes :/

[michbsd]

I switched to neovim - and the issue does to occur there.. 🤷🏼

[acarl005]

I'm finally taking a look at this. Possibly related to #5166?

[acarl005]

@michbsd I suspect the issue has to do with the terminfo database on your remote server. I was finally able to reproduce this error by changing the value of TERM. Setting TERM=vte-256color finally reproduced this error.

Can you run echo $TERM on your host and post the value? I also wonder if setting export TERM=xterm-256color on your server might fix the issue?

[michbsd]

xterm-256color

I switched to neovim, which does not exhibit the behavior

[dannyneira]

Hi Folks, this has been resolved in latest version of Warp. Closing as resolved, but please update and let us know if any issues.
