# Objective Fix the Agent sidebar header being two pixels lower than the title bar on Linux. This only affects Linux with client-side decorations: the main title bar uses a negative one-pixel margin to overlap the client-drawn window border, while the sidebar previously used a positive one-pixel margin on every platform. Fixes #53739 ## Solution Match the sidebar header spacing to the window decoration mode: - Use `-1px` top margin for client-side decorations. - Preserve the existing spacing for server-side decorations. - Apply the fix to both the thread list and archive headers. ## Testing - Manually tested on Linux. This only affects Linux because its client-side window decorations require the adjusted title bar offset. ## Self-Review Checklist: - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments - [x] The content adheres to Zed's UI standards ([[UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) and [[icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md)](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md) guidelines) - [ ] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable ## Showcase After this change： [2026-08-02 18-20-19.webm](https://github.com/user-attachments/assets/1ef13ff2-2036-442b-8bcc-74ebeb8436c7) --- Release Notes: - Fixed misaligned Agent sidebar headers on Linux.
