Electron Apps Causing System-Wide Lag on Tahoe

This script detects apps with not yet updated versions of Electron.

See:

• electron/electron#48311 (comment)
• https://mjtsai.com/blog/2025/09/30/electron-apps-causing-system-wide-lag-on-tahoe/

Fixed versions:

• 36.9.2
• 37.6.0
• 38.2.0
• 39.0.0
• and all above 39

Original gist: https://gist.github.com/tkafka/e3eb63a5ec448e9be6701bfd1f1b1e58

Temporary workaround:

Run

launchctl setenv CHROME_HEADLESS 1

on every system start. The CHROME_HEADLESS flag has a side effect of disabling Electron app window shadows, which makes them ugly, but also stops triggering the issue.
