June 2026 monthly summary focused on delivering a security-and-operations improvement in linuxdeepin/dde-daemon: enabled read-write configuration for the password encryption algorithm, allowing authorized applications to modify the setting while preserving access control. Implemented support for multiple algorithms (sha512, sha256, yescrypt, sm3) and wired the change through account DSG configuration, increasing flexibility for password policy updates without code redeploys.

March 2026 monthly summary for performance review focusing on business value and technical achievements across linuxdeepin/dde-launchpad and linuxdeepin/dde-shell. Delivered stability and a smoother user experience by fixing memory leaks, enhancing notification UX, hardening UI interactions, and improving input focus management. Tech stack demonstrated includes Qt/QML, C++, and robust UI event handling with a focus on maintainability and testability.

February 2026 focused on strengthening UI reliability, visual clarity, and asynchronous asset loading across dde-shell and dde-launchpad. Delivered targeted fixes and a styling overhaul that together improve user experience, reduce edge-case failures, and enable smoother app onboarding.

Month: 2026-01 | Repository: linuxdeepin/dde-shell Feature delivered: Notification Bubble Entrance Animation Improvements. Implemented optimized entrance animation logic to prevent overlap and boost performance. Key changes include reducing pre-animation processing from O(N) to O(1), and updating the bubble layout so that when a new bubble appears, only the immediately preceding bubble’s position is recalculated. Code changes are in panels/notification/bubble/package/main.qml. Commit: beda4022f5cbcccb0fa13aeda51d63ac907abc1f. PR/log notes: fix: Optimize the entrance animation logic for notification bubbles; Bug reference: BUG-320719. Testing and validation included simulated bursts of notifications to verify queuing, sequential playback, and correct behavior when the bubble count exceeds the maximum. Key achievements for the month: - Optimized notification bubble entrance animations to prevent overlap and improve performance (pre-processing reduced to O(1)). - Refined layout logic to update only the immediately preceding bubble, ensuring robust positioning with rapid bursts. - Verified queuing and sequential playback under burst scenarios, with smooth transitions and no visual glitches. - Delivered targeted changes in a core UI module with clear gain in perceived responsiveness and reliability.

November 2024: Delivered a critical bug fix for dde-session-shell to ensure login wallpaper stability after system upgrades, improving first-login visuals and reducing post-upgrade background glitches. The change prevents an unprocessed native image from being set as the login background, addressing a long-standing edge-case in the upgrade path. The work involved targeted investigation, patch application, and validation across upgrade scenarios, with a focused commit and clear impact on user experience.
