What's Wrong?

Platform: Windows 11
App: Claude Desktop (Claude Code)

Description:
The Windows native title bar buttons (minimize, maximize, close)
overlap with the Claude Desktop interface toolbar buttons, making
some UI controls inaccessible or visually conflicting.

Steps to reproduce:

1. Open Claude Desktop on Windows 11
2. Observe the top-left/right area of the window

Expected behavior:
UI buttons should not overlap with Windows window controls.

Actual behavior:
Claude's toolbar icons overlap with the native Windows title bar controls.

Display scaling: (add yours, e.g. 125%)
Screen resolution: (add yours, e.g. 1920x1080)

What Should Happen?

The Claude Desktop toolbar buttons should be positioned
below or separate from the Windows native title bar area,
with no visual overlap.
