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: Mac OS Sierra 10.12.3
Hyper.app version: 1.3.1.1628

Relevant information from devtools (CMD+ALT+I on Mac OS, CTRL+SHIFT+I elsewhere): “Uncaught TypeError: Cannot read property ‘wcNode’ of undefined” (uh, it’s minified, but the code looks like it’s trying to do something related to splitting the long string into multiple lines.
The issue is reproducible in vanilla Hyper.app: Is Vanilla

Issue

I’m working in a ruby cli and printing large objects. At a certain size, the UI just stops printing mid-string and hangs. I’ve tested it out locally just by making big strings, and it appears to be somewhat varied in how big the line is before it blows up.

open new hyper window
open new ruby console: irb
print a string that is made up of 1000 Xs: puts "X" * 1000. This one works
print a string that is made up of 10000 Xs puts "X" * 10000. This one breaks. UI appears to hang. Opening developer tools shows the console error “Uncaught TypeError: Cannot read property ‘wcNode’ of undefined”.

Substitute larger numbers if 10000 works for you. In my testing I’ve seen it handle 5000 just fine some times and blow up at 1250 other times.

Note that I am able to echo large lines from bash, cat a long single-line file, etc no problem. So there might be something unique to ruby going on here?
