[BUG] Claude in Chrome extension causes persistent yellow screen border on all monitors (Windows)

What's Wrong?

After using Claude Code with the Claude in Chrome extension, a persistent yellow border appeared around the edge of all three of my monitors. This is the Windows "screen capture active" indicator that appears when an application is using the Windows Graphics Capture API.

The border persisted even after:

• Closing Chrome completely
• Killing DWM (Desktop Window Manager)
• Restarting the graphics driver (Win+Ctrl+Shift+B)
• Killing all RuntimeBroker processes

Only a full system restart cleared the border.

Windows Event Viewer logged the following at the time the border appeared:
Event: WindowsBlackScreenDiagnosticsV1
P1: DWM
P3: ColorBits
P4: Hotkey

This suggests the Chrome extension's screen capture functionality (used for screenshots/GIF recording) did not properly release its capture session, leaving Windows stuck in a "capture active" state.

What Should Happen?

Screen capture sessions initiated by the Chrome extension should be properly released/terminated when:

• The browser tab or window is closed
• The extension disconnects from Claude Code
• The Claude Code session ends
• Chrome is closed

The Windows screen capture indicator should not persist after the capture operation completes or the application closes.

Steps to Reproduce

Steps to Reproduce

1. Launch Claude Code with the Claude in Chrome MCP extension enabled
2. Use the browser automation tools (exact trigger uncertain - possibly screenshot or GIF recording functionality)
3. Close Chrome or disconnect the extension
4. Observe: Yellow border remains around all monitors
5. Attempt standard fixes (restart DWM, graphics driver, kill RuntimeBroker) - border persists
6. Only full system restart clears the border

Additional Information

• Multi-monitor setup: 3 displays
• The yellow border is the Windows privacy indicator shown when apps use the Windows.Graphics.Capture API
• Color Filters in Windows Settings confirmed OFF (not the cause)
• The "Hotkey" value in the Windows event log is puzzling since no keyboard shortcut was deliberately pressed - suggests the extension may have programmatically triggered something
