[Bug] Midnight Commander and msys

[ajtak-angelus]

Version Information

Cmder version: v1.3.24
Operating system: Windows 10 22H2

Cmder Edition

Cmder Full (with Git)

Description of the issue

I connect from cmder using ssh (cmder\vendor\git-for-windows\usr\bin) to the linux server and run midnight commander (mc). And as soon as I press ctrl+o, all the text under mc disappears. This has been happening since git-for-windows 2.27.0.
But I would like to use newer versions of git-for-windows because of the mouse in mc and other graphical improvements.
Can you please advise?
Thank you!

How to reproduce

1. ssh user@server
2. run mc
3. press ctrl+o
4. text disappears

Checklist

• I have read the documentation.
• I have searched for similar issues and found none that describe my issue.
• I have reproduced the issue on the latest version of Cmder.
• I am certain my issues are not related to ConEmu, Clink, or other third-party tools that Cmder uses.

Hi, I've done some tests, and it seems that this issue is happening due to ConEmu. Can you please test with some other terminals? Additionally, can you please install the vanilla ConEmu (not with Cmder) and test using the built-in ssh.exe in Windows?
Doing these tests may help us investigate the issue.

[ajtak-angelus]

I've tested it only in vanilla ConEmu and there mc even flashes the screen. Tested both with ssh directly in Windows and from git. Anything else I should test?

[DRSDavidSoft]

Can you please dump SET to list the environment variables? Especially the TERM variable, if set

Any news? Thanks

[DRSDavidSoft]

Sure, could you please tell me which Linux you are using, and also please enter the printenv command on your Linux machine and post the results as well.

This is because there might be an env variable set on the Linux machine that might be causing this.

Lastly, please open conhost.exe (the Windows Command Prompt) and connect using SSH to the Linux machine. Verify that midnight commander is working as intended. Then open a new conhost.exe and enter SET to dump the environment variables of a non-Cmder Window.

This will help us compare the variables and identify any differences that might be causing this.

Another thing that might be causing the issue might be the /etc config files that might have either been customized by the Linux flavor you are using, or modified by yourself.

If you can further more connect to a different Linux host, such as a VM or even Microsoft WSL to see if the same issue still exist, that would also be helpful.

With this steps we will hopefully be able to identify the problem and solve it.

Hey. Hey,
if I start conhost, mc behaves normally.
And I used ssh from \cmder\vendor\git-for-windows\usr\bin
I use the Debian distribution everywhere. So I tried Ubuntu and the same problem.
