Windows line wrap doesn't linefeed

[AE9RB]

Both V6 and V5 show this behavior in Windows. It works fine in Linux. Run an example and type past the end of the line; you'll be typing over the first line. Backspace past the start of a line and the input starts moving up the screen. Reproduces in PowerShell and CMD in the old terminal (conhost.exe), new Windows Terminal, and VSCode terminal.

Indeed,
At least versions 4, 5 and 6 are impacted (repaint / refresh is buggy).
And latest panics !
I don't have access to a windows machine at home and only limited access at work.
I may be able to reproduce with Wine.
Regards.

I cannot reproduce with Wine. But I will try to debug and fix it on Windows.

Could you please confirm that it happens only on Windows 10 ?
Currently rustyline is using ENABLE_WRAP_AT_EOL_OUTPUT (which is activated by default).
And there seems to be a bug when you mix both ENABLE_WRAP_AT_EOL_OUTPUT and ENABLE_VIRTUAL_TERMINAL_PROCESSING: microsoft/terminal#349
Before Windows 10, ENABLE_VIRTUAL_TERMINAL_PROCESSING is not supported so we are not impacted.

As a temporary/dirty workaround, you can disable colors (ColorMode::Disabled) to make line wrapping works on Windows 10.

Should be fixed in 6.1.2
