Description

  • I am on the latest Hyper.app version
  • I have searched the issues of this repo and believe that this is not a duplicate
  • OS version and name: macOS Big Sur 11.4 (20F71)
  • Hyper.app version: Hyper 3.1.0-canary.5 (stable)

Issue

I've only been able to reproduce this in the following circumstances:

  • Brand new Hyper bootup
  • Using ZSH

Doesn't happen with Terminal.app

It happens even with vanilla .zshrc

▲  ~/ zsh --version                                                                       17ms 
zsh 5.8 (arm-apple-darwin20.2.0)

Research direction

Start by reproducing the startup behavior on macOS Big Sur with Hyper 3.1.0-canary.5, ZSH, and a vanilla .zshrc, then compare it with Terminal.app. The issue is complete when the stray % symbol no longer appears during a fresh Hyper startup.
