Description

In Atom 1.23.3 the rendering stops after around ~800k lines and nothing is displayed. On a recent master Atom can render ~1 million lines and then the rendering looks really bad.

@ungb This might be due to the electron upgrade. We should add large files to the testing docs.

Steps to Reproduce

1. Open this file in Atom https://gist.github.com/Ben3eeE/22ad32cbd9106bad16648d1c23f85709
2. Scroll to the bottom

Expected behavior: All lines to render correctly

Actual behavior: Bad rendering

Reproduces how often: 100%
