2. Press Ctrl + r
3. See error

Expected behavior Manual refresh of application

Screenshots

Desktop (please complete the following information):

• Terminal name and version: iTerm2 3.4.23
• Shell name and version: zsh
• jwt-ui version: 1.1.0

This will make the (zsh) terminal unusable too, since it will write scroll-characters. Using zsh 5.8 (x86_64-ubuntu-linux-gnu) with the main branch of the jwt-ui on Ubuntu 20.04 I can reproduce the behavior.

Scroll characters after jwt-ui died (ctrl+c wont help):

[deepu105]

I saw the scroll character issues and I thought I fixed it by disabling mouse capture

[deepu105]

Ok seems like I was not doing DisableMouseCapture on panic hook
