Antigravity becomes unresponsive on Ubuntu 24.04 (99% CPU usage in zygote process)

I’m experiencing a critical issue with Antigravity on Ubuntu 24.04.4 LTS (X11/GNOME).

Antigravity starts but immediately becomes unresponsive. One of the Antigravity processes continuously uses 99-100% CPU, and the application never becomes usable.

I have tested many different Antigravity package versions, and all of them exhibit the same behavior.

Environment

  • OS: Ubuntu 24.04.4 LTS
  • Desktop: GNOME
  • Session: X11
  • Architecture: x64

Affected Versions

The issue occurs on all of the following package versions:

1.23.2-1776332190 to 1.18.3-1771473975

Current Version

antigravity --version

1.107.0
cc6cd32816d350ee4a1ea2b4694b43f749418957
x64

Process Information

ps -ef | grep antigravity

One process consistently consumes nearly all CPU:

/usr/share/antigravity/antigravity --type=zygote

Example:

ubuntu 381929 ... 99% CPU
/usr/share/antigravity/antigravity --type=zygote

Troubleshooting Already Performed

I have already tried all of the following without success:

  • Started with a completely fresh user profile
  • Cleared all Antigravity cache and configuration
  • Started from terminal with verbose logging
  • Started with --disable-extensions
  • Started with --disable-gpu
  • Started with --new-window

Questions

  1. Is there a known regression in recent Antigravity releases?
  2. Are there any additional debugging steps I can perform?

Thank you.
