I type some text and then use the arrow keys to go back a few characters and then when I advance it re-paints the text but a few characters forward. I'm also not able to bring the cursor right back to the start of the text:

Hyper 1.0.0
Electron 1.4.7
win32 x64 10.0.14393
Shell: Git Bash v2.11.0
Related to #1174
I'm not getting the same issue when using the Windows Command Prompt, just when using Git Bash as the shell.
@mtwalsh could you try to reproduce on this branch?
I don't have Windows PC to test :(
@dotcypress Just tried it with that branch, can still reproduce it.
This might be an upstream issue with pty.js. I mentioned in #1174 that this problem occurs with the VSCode integrated terminal as well.
Yes, same issue for me on that branch I'm afraid.
I'm pleased to report this has been fixed in v1.2.1.
Thank you!
