Environment

Windows build number: 10.0.18362.388
Windows Terminal version (if applicable): 0.5.2762.0

Any other software? SSH (from Windows 10), GNU screen on host

Steps to reproduce

Ssh into remote host.
Start GNU screen (screen)
Type cd and the first few non-unique characters of a directory.
Press tab key to trigger autocomplete

Expected behavior

The cursor should stay where it is, nothing should be autocompleted. Further keystrokes should continue from this location,

Actual behavior

The cursor jumps to the end of the current line, further keystrokes wrap on subsequent line, backspace makes a big mess.

Note this behaviour does not happen outside of GNU screen - it's some weird interaction between the behaviours that Windows Terminal implements compared to the term type of "xterm-256color" that it reports.

There are also lots of bugs with the cursor and GNU screen if you vertically split the screen (ctrl-a |).

@owainkenwayucl can you give me more details about the remote host? What OS is it running? What version of screen is it running?

This is suspiciously similar to #1825 which was fixed in #3015, but I'd love to know if it is a unique problem.

If you're not running CentOS on the remote, can I get some additional info? What is TERM set to, and what's the output of infocmp?

Hi,

Sure, anything I can do to help.

The remote host is running RHEL 7 and screen 4.2.1

The value of $TERM outside Screen is xterm-256color

Based on your comment that the other bug has been fixed in a recent update, I've updated Terminal to 0.6.2952.0 from the Windows Store and this bug appears to be fixed so can be closed?
