Issue
webGLRenderer: true
Cursor position is shifted when types.
The more characters are typed, the more the cursor is shifted.

If disable webGLRenderer everything works as expected.
webGLRenderer: false

updated:
seems that issue could be reproduced
- if hyper is opened as fullscreen (at macos)
- if there is only on pane
