Same here. This bug starts to occur after I switch from a tab in which I was using Hydrogen to another one. Here are my specs:

Atom: 1.35.1 x64
Electron: 2.0.18
Chrome: 61.0.3163.100
Node: v8.9.3
OS: Ubuntu 18.04

Any update on this? I'm getting the same thing and it's making Atom virtually unusable.

This is from a function that calls an Atom function. Similar to #571
