Terminal stops displaying text

• 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: Ubuntu 20.04.3
• Hyper.app version: 3.1.3
• Link of a Gist with the contents of your .hyper.js: https://gist.github.com/linaori/40571b7cf965a5cd0ac321d7b8221dd8
• Relevant information from devtools (CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere): N/A
• The issue is reproducible in vanilla Hyper.app: Not 100% sure, I think it is.

Issue

The left pane is watch sensors and the right pane is docker-compose up logs:

This seems to randomly happen when the app is minimized. Hovering over links still works and clicking them will still open the link.

When I then press CTRL+C to cancel watch sensors

Typing "a" gives me:

Typing "s" after and then going back to the "a":

When I then restart the terminal and type "a" again, I get this:

Seems like something is breaking in the rendering. I'm using zsh, though that shouldn't matter I think as I never have this in Terminator.

Start by reproducing the display failure on Ubuntu 20.04.3 with Hyper.app 3.1.3, minimizing the app while running watch sensors and docker-compose up. Trace the terminal rendering behavior using the provided screenshots and configuration gist; done means text remains visible and interactive after minimizing, restoring, and typing.
