I can repro it on 2.0.0 beta 1 with Emacs mode.
Looks like some overflow when possible completion options don't fit on one screen.

I believe this may be captured in #663.

I think I have this same issue, I'd rather not duplicate ticket.
At $HOMEPROFILE dir I did cat C:\users\<me>\.ssh\<tab><tab>

And Received:

 UpArrow Delete Delete Delete Delete Delete Delete Delete Delete Delete Delete Delete Delete p i n g Space Enter
 s s h Space v m Backspace Backspace Backspace Backspace Backspace Backspace c a t Space ~ / . s s h Tab Tab Tab Tab Tab

I think this was fixed in 2.0.0-beta3 - maybe you can give it a try?

[erichiller]

Again, apologies for the delay @lzybkr - It does work when running vanilla powershell now. If I use oh-my-posh then it appears the script block is not being processed or some such, the second time around. I put an issue there with far more detail if you think this is related. oh-my-posh 116

OK, I'm resolving as fixed by #704 and #783.
