1. Show screenshot where both ConEmu and corresponding RealConsole are visible.
2. Copy information (text!) from ConEmu/About/SysInfo, paste to gist and post link here.

I think this is because bash changes codepage to UTF-8.
Here is a screenshot for RealConsole

sorry
this is RealConsole:

chcp 65001 than ok:

I debugged lxrun.exe and found it begins repeat after SetConsoleOutputCP.

Write a program that SetConsoleOutputCP(65001); can reproduce the bug.

This because current codepage is not DBCS but the buffer contains DBCS data.

I can reproduce this problem on Windows 10 Pro Insider Preview 14986.
And it works well on Windows 10 Build 14393 (Not preview version), though.
Here is the screenshot on the former:

Besides, I find a similar fixed bug reported in 2012. Hope it will help. :-)

The current issue looks like duplicate of gh-945 and actually, looks like a bug in Microsoft console API (not confirmed or fixed yet).
It doesn't relate to gh-577 because ConEmu works properly on any Windows up to 8.1
