GPU load bug and Autofill bug are two separate, completely unrelated issues.
I’m happy to refer to a better workaround if you have one?
1. workaround for high GPU load by Electron apps (what this HN thread is about) — see the command here: https://github.com/electron/electron/issues/48311#issuecomme...
2. unrelated workaround for scroll bug - defaults write com.google.Chrome NSAutoFillHeuristicControllerEnabled -bool false
Too late to edit now, but yep, the launchctl headless workaround works around Electron lagging the system, and the scroll bug works around macOS lagging the system. Thanks!
