[Bug / Instability] Gemini 3.7 Flash performance degradation in Google Antigravity

I am encountering severe performance drops and unexpected behavior while using the Gemini 3.7 Flash model inside Google Antigravity. The model frequently produces bugs, ignores prompt constraints, and fails to return reliable outputs.

I am facing the same issues with Gemini 3.7. For me its on Gemini chat window.
