What's Wrong?

Environment

• OS (host): Windows 11 Pro 25H2 26200.8875
• Remote: WSL Ubuntu 24.04, connected via Remote-SSH
• VS Code version: 1.134.0
• Claude Code extension version: 2.1.260
• Model in use: Opus 5 (1M context)

Description

The floating Claude Code input bar (the pill showing "ctrl esc to focus or unfocus Claude", the model selector, and the "Edit automatically" toggle) is rendered as an always-on-top overlay anchored to the editor area. It does not respect VS Code's native "Maximize Panel" layout state.

When the bottom panel (Problems / Output / Debug Console / Terminal / Ports / Comments) is maximized via the native VS Code command, this floating widget stays on screen and visually covers part of the maximized panel's content — in my case, several rows of the Problems tab (TypeScript/YAML diagnostics) were hidden behind it.

What Should Happen?

Expected Behavior

When a panel is maximized, it should either:

• fully cover/hide the floating Claude Code widget (as it does for regular editor content), or
• the widget should reposition/dock so it no longer overlaps panel content.

Actual Behavior

The floating widget keeps its fixed position and z-index on top of the maximized panel, permanently occluding part of it. There is no obvious way to move or dismiss it without unfocusing Claude entirely (Ctrl+Esc).

Workaround

• Ctrl+Esc to unfocus/collapse the Claude bar before maximizing the panel.
• Drag the panel to the Secondary Side Bar instead of maximizing it.
• Resize the panel manually instead of using "Maximize Panel".

Additional Context

This only reproduces with the panel maximized; normal (non-maximized) panel layouts don't show the overlap since there's still editor space for the widget to occupy without covering panel content.

Steps to Reproduce

1. Open a workspace with the Claude Code extension active (input bar visible/floating).
2. Open the bottom panel and select any tab (e.g. Problems).
3. Click "Maximize Panel" (or double-click the panel tab area) to expand it over the full editor region.
4. Observe that the Claude Code floating input bar remains on top of the maximized panel, obscuring part of its content.
