[Bug Report] High CPU Usage (400%) by language_server_macos_arm on latest macOS

Description: I am reporting a critical performance issue with the latest build of Antigravity on macOS (Apple Silicon). The language server process consistently consumes excessive CPU resources, rendering the machine unresponsive and causing overheating.

Environment:

  • Application: Antigravity 1.15.8 1.104.0

  • OS: macOS Tahoe 26.2 (25C56)

  • Architecture: Apple Silicon (ARM64)

  • Process Name: language_server_macos_arm

Symptoms: Upon launching the application, the language_server_macos_arm process spikes to approximately 400% CPU usage according to the Activity Monitor. This high load persists even when the editor is idle and no heavy indexing should be occurring.

Reproduction Steps:

  1. Launch Antigravity.

  2. Open a workspace/project.

  3. Observe Activity Monitor; the specified process immediately jumps to high CPU usage and does not throttle down.

Expected Behavior: The language server should idle efficiently when not actively indexing or analyzing code.

Has this regression been tracked? Any assistance would be appreciated.

same here, noticed it spawned many language_server_macos_arm processes

UPDATE: I noticed that one of my prompts generated a .css file that was 190GB large .. I undid the changes in git and it went back to 7KB . idk how but now it works fine ? os maybe check your file sizes .

I have almost the same issue, since long days on Ubuntu 24

My laptop is refreshing always when the agent is launched, i’ve tried a lot of tricks (IDE global settings on search / watcher excludes files, clean code project in case of, ‘cpulimit’ package to launch with process id of antigravity to target this use)
i’ve udpated the soft today also

it’s not a normal situation, it’s literaly draining the battery of laptop + over using CPU

Same problem here, with the same configuration. I’ve had to stop and relaunch the app every 5-6 tasks.

battery getting destroyed from this since mid December. No update has fixed it. Apple Silicon M3 running extremely hot, MacBook sounds like fighter jet, drained me from 98% battery to 54% in 20 minutes
