winpty interoperability

[pyhedgehog]

Versions

ConEmu build: 160607 x64 OS version: Windows 7 Enterprise SP1 x64 Other versions:

• cygwin64 2.5.1-1
• bash 4.3.42-4
• Far Manager 3.0 (build 4242) x64
• mintty 2.3.5-0
• winpty-cygwin64 0.2.2
• conemu-cyg-64 0.7.4

  Problem description

Far under winpty under conemu+connector shows empty lines after full-width lines (see screenshots).

Steps to reproduce

1. Run ConEmu
2. Run cygwin shell via cygwin-connector
3. Run far via winpty: console --mouse far or (winpty --mouse far for newer winpty)

   Actual results

Expected results

Additional details

It doesn't works under plain ConEmu and this is OK, because it's also broken under conhost. But cygwin-connector as far as I understood is something like mintty - cygwin-style console emulator. If I'm wrong could you please help me to formulate bug report to winpty.

Also following details should be noted:

• $TERM is xterm under mintty and xterm-256color under connector, but changing it doesn't changes anything.
• Using winpty under ssh (this is major usage of such feature) doesn't changes anything.
• Using winpty under screen doesn't changes anything.
• Upgrading winpty to 0.3.1 doesn't changes anything.

Screenshots:

• conemu-winpty-mintty* - winpty+far under mintty works fine (so it's achivable)
• conemu-winpty-raw* - winpty+far under raw conhost has broken output (so don't blame conemu)
• conemu-winpty-conemu* - winpty+far under plain conemu also has broken output (just to check)
• conemu-winpty-connector* - winpty+far under conemu+connector has broken output (I think it's a bug)

PS: Will conemu -basic of logs help investigation?

@Maximus5, am I used wrong repository to report?

[Maximus5]

No, it's correct place. But answer requires investigations...
