My cursor lagging is not a small concern. It disrupts the flow between code being re/written and the mental model I'm trying to pour out.

Text input lag is an issue every editor has to deal with, and many go to extreme lengths to optimise it. Electron makes it far more difficult than most editors to fix, and every lag issue opened on VS Code seems to get decent attention, (and patches), and comparisons to Sublime Text.

Seems to be something I'm not alone in caring about.
