ConEmu/cygwin newlines don't perform carriage return functionality

Question

I upgraded Cygwin and now Bash is acting weird. Newlines aren't always returning the cursor to the left side of the screen, but sometimes they do. Here is what I'm experiencing:

$ echo hello
            hello
                 Thu Jan 30 08:31:33 :~
$ python3
         Python 3.6.9 (default, Jul 21 2019, 14:33:59)
[GCC 7.4.0] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 56+23
         79
           >>> 2+3
                  5
                   >>> exit()
                             Thu Jan 30 08:31:46 :~
$

I have TERM=xterm-color, and I've tried TERM=cygwin and just TERM= with no difference in behavior.

Another strange thing is that the less command will mess up the newlines when I first open a file, or page down with Ctrl-F, but if I page up or scroll up or down one line at a time, the formatting is fine.

ls -l works fine. cat works fine.

hello @matt, has you found a solution? – Yeray Rodriguez Feb 07 '20 at 15:14 — Yeray Rodriguez, Feb 07 '20 at 15:14

I've determined it's ConEmu. It has something to do with my task command:

C:\cygwin64\bin\bash.exe --login -new_console:P:"<Standard VGA>"

I use this so the background is black. Also, when I logout, the tab closes instead of remaining open.

The default command doesn't have the newline problem, but has the problems stated above:

set CHERE_INVOKING=1 & set "PATH=%ConEmuDrive%\cygwin64\bin;%PATH%" & %ConEmuBaseDirShort%\conemu-cyg-64.exe -new_console:p %ConEmuDrive%\cygwin64\bin\bash.exe --login -i -new_console:C:"%ConEmuDrive%\cygwin64\Cygwin.ico"

Edit: Of course, it has nothing to do with the -new_console:P:"<Standard VGA>" and everything to do with running bash with %ConEmuBaseDirShort%\conemu-cyg-64.exe. I don't know what it does exactly - I need to look into it further.

Edit #2: It turns out there's an issue with arrow and delete keys being disabled by conemu-cyg-64.exe: https://github.com/Maximus5/ConEmu/issues/2035.

Edit #3: Downloading the latest developer snapshot (which is 2020-01-31 at this time) of Cygwin at https://cygwin.com/snapshots/ fixed the problem with the arrow and delete keys for me.

$ unxz cygwin1-20200131.dll.xz
$ mv cygwin1-20200131.dll /bin/cygwin1.dll

Of course, that isn't going to work while Cygwin is running, but you get the idea.

For me updating to the latest ConEnum release (Version 1.3.18.1106) solved the problem.

No it does not (as of 2021-05-31) – BetaRide May 31 '21 at 11:28
Even the latest dev-snapshot (2021-05-07) does not help. – BetaRide May 31 '21 at 11:46

For me disabling "Inject ConEmuHk" helped.
