What's Wrong?

In the Claude Code tab of the Claude Desktop app on Windows (with the window maximized / full screen), the main right-side vertical scrollbar's clickable hitbox does not extend to the right edge of the window. Slamming the cursor to the far right (Fitts's law target) lands outside the scrollbar, so click-to-scroll fails.

This does not happen in the Claude Chat tab of the same app — the Chat tab's scrollbar is flush to the window edge and behaves correctly. The two tabs use different scrollbar/container rules.

What Should Happen?

The main vertical scrollbar's hitbox should extend all the way to the right edge of the window (matching the Claude Chat tab), so the cursor can be thrown to the screen edge for reliable click-to-scroll.

Error Messages/Logs

Steps to Reproduce

  1. Open the Claude Desktop app on Windows 11 and maximize the window (full screen).
  2. Switch to the Claude Code tab.
  3. Open a conversation long enough to require scrolling.
  4. Move the mouse cursor to the far right edge of the window, level with the scrollbar track.
  5. Click — the click misses the scrollbar (cursor is outside the hitbox).
  6. Repeat in the Claude Chat tab — the same gesture works correctly.

TL;DR

The issue can be fixed by adjusting the CSS or layout rules for the scrollbar in the Claude Code tab to match the Claude Chat tab.

Guidance

  • Investigate the CSS styles or layout configurations applied to the scrollbar in the Claude Code tab and compare them with the Claude Chat tab to identify any differences.
  • Check the HTML structure of both tabs to ensure that the scrollbar is properly contained within its parent element and that there are no overlapping elements that could be interfering with the clickable area.
  • Consider adding a CSS rule to explicitly set the width of the scrollbar or its container to ensure it extends to the right edge of the window.
  • Test the fix by verifying that the scrollbar's clickable area now extends to the right edge of the window in the Claude Code tab.

Example

No code example is provided as the issue does not include specific code snippets or details about the implementation.

Notes

The fix may require modifications to the CSS or layout rules specific to the Claude Code tab, and care should be taken to ensure that any changes do not introduce new issues or affect other parts of the application.

Recommendation

Apply a workaround by adjusting the CSS or layout rules for the scrollbar in the Claude Code tab, as the root cause appears to be related to the specific implementation of the scrollbar in that tab.
