Environment

Windows Terminal version (if applicable) :0.10.721.0

Any other software?

Steps to reproduce

Not too sure what caused it but I know I have a really long path in the prompt. It's fine when I interact with it at first. But after attempting to run the command, and pasting the same path again, the cursor goes crazy. Specifically, I was ctrl+left and it started happening. Here's a gif:

  1. paste long path/command
  2. run it (mine failed, derp)
  3. press up (populates prompt)
  4. ctrl+left to browse the input

Actual behavior

cursor goes wack

reflow bug

This may be a combination of the perfect wrap bug and this issue where sometimes the conpty host is off by one width

@carlos-zamora what's your prompt set to in powershell? I can't get this to repro with

$esc = [char]27; function prompt() { "${esc}[41mhas a newline${esc}[m`n${esc}[33;40mha ha ha${esc}[m> " }

Was there any actual resizing involved?

I guess it's just a reflow bug, not resize.

I have a custom prompt, but it's basically just the Powerline theme from oh-my-posh. I'm wondering if this is just another manifestation of #2432?

I mean, I'm sure it's possible, though that one I'm positive that conpty and Terminal have the same contents in the buffer, while this one I'm a little more scared. I'll try oh-my-posh and see if that repros it for me.

Ok. We somehow couldn't get a repro of this. We're thinking it might be a powerline issue? But we're just gonna close this out until it pops up again. Spooky
