Bug Report: Antigravity v2.3.1 (linux x64) - There is no icon or three dots to open Auxiliary Pane

Google Antigravity

I Updated Antigravity to v2.3.1, i am using Linux x64.

After updating i notice that there is no way to open Auxiliary Pane.

No icon or any option.
Three dot is also completely gone from the right top.

Three dot and the Auxiliary Pane both shows with only these methods:

  1. when i click on changed file or any file in the chat.
  2. by using shortcut Ctrl + Alt + B.

please fix this UI issue.

3.5 Flash is getting stupid and ignoring a lot of things.
It seems like it ignores a lot of reasoning to give answer faster as compare to claude sonnet 4.6 which seems to be better in reasoning than Gemini 3.5 Flash.

I Wonder why is that, 3.5 Flash was suppose to be better than Sonnet 4.6 but it’s worse than that and for some reason it is getting even more worse.

I kindly request to google team, stop doing experiments on models which were stable before. You are breaking it. Do it in development not in production.
i have paid account for using Antigravity and it is making me regret the decision.

Please keep the model and the Software stable.

New Technical Findings:

  • Root Cause: The Auxiliary Pane icon and the three-dot menu are not actually deleted from the UI; they are rendering directly underneath the default OS window controls (Minimize/Maximize/Close buttons) on the Title Bar.
  • F11 Proof: Pressing F11 to enter full-screen mode hides the OS title bar, which immediately reveals the missing elements.

Steps to Reproduce / Workarounds:
The elements remain invisible during normal windowed mode unless forced open via specific context actions:

  1. F11 Shortcut: Switching to full-screen mode makes them visible.
  2. Context Trigger: Clicking a changed file or a file link within the chat forcibly exposes them.
  3. Hotkeys: Using Ctrl + Alt + B opens the pane via shortcut, bypassing the broken UI icon.
