What's Wrong?

On Windows, when opening a new window in the Claude Code desktop app, the draggable title bar region at the top of the window (the area you click and drag to move the window) is no longer present. Previously, new windows had a bar at the top that could be clicked and dragged to reposition the window. After a recent update, this bar is gone in newly opened windows, so there is no visible area to grab, and the window cannot be moved with the mouse in the normal way.

Steps to reproduce:

1. Open the Claude Code desktop app on Windows.
2. Open a new window.
3. Try to move the new window by clicking and dragging its top edge.

Expected: The new window has a draggable title bar region at the top, as before, so it can be repositioned by dragging.

Actual: The draggable title bar region is missing in the new window, and there is no area that responds to click-and-drag for moving the window. The only workaround is using the keyboard (Alt+Space -> Move).

This looks related to existing window-drag-area issues (#51140 on macOS, #52699 on Windows title bar controls overlapping), but this specific regression is that the drag area is missing entirely in new windows.

What Should Happen?

New windows should have a draggable title bar region at the top (as in previous versions), so the window can be moved by clicking and dragging with the mouse.

Steps to Reproduce

1. On Windows, open the Claude Code desktop app.
2. Open a new window from the app.
3. Look at the top of the new window: the draggable title bar region that used to be there is missing.
4. Try to move the window by clicking and dragging the top of the window — nothing happens; there is no draggable area.

Workaround: the window can only be moved via keyboard (Alt+Space -> Move -> arrow keys).

Additional Information

This report is about the Claude Code desktop app GUI on Windows (not a terminal), which is why Terminal/Shell is set to "Other". The issue is specifically about the window chrome of newly opened windows: the draggable title bar strip that previously allowed moving the window is no longer rendered/registered as a drag region.
