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.
