Lu Yaning

Luyaning developed core window management and multi-seat input features for the felixonmars/treeland repository, focusing on stability, reliability, and user experience in complex desktop environments. Over six months, Luyaning implemented robust multi-monitor support, real-time performance monitoring, and centralized seat management, using C++, QML, and the Qt framework. The work included refactoring display output logic, enhancing keyboard shortcut handling, and improving crash resilience during workspace transitions and device changes. By modernizing code structure and introducing modular input routing, Luyaning enabled scalable multi-user setups and smoother desktop interactions, demonstrating depth in system programming, resource management, and cross-repository collaboration for maintainable codebases.

Nov 1, 2024

November 2024 performance summary: Focused on stability, UX polish, and cross-repo correctness across felixonmars/treeland and felixonmars/waylib. Demonstrated strong capabilities in multi-display window management, desktop lifecycle improvements, crash prevention, and QML/UI correctness. These efforts reduced failure modes in workspace transitions and multi-monitor setups while delivering a more consistent user experience and easier maintainability. Key deliveries and business value: - Show Desktop lifecycle and visual consistency improvements (treeland): robust desktop transitions, stable window visibility, correct surface handling, reliable restoration when switching workspaces, and improved animation timing. Commits include 7b70adc648c9e4f12b9e03730a3ac34bd8d7bed2; ec2839a47d93670c9e8559f4e8ba2ec6437538a7; 38d4c955e924b588a277ee56d4e9863db663efe3; 6406f62ed37692aeec1c22aac6ed53d454fa45af; ab79e229d6c17032941ab54288e71a9487cb7286; 4370d03e5f92d5bf525064fe2bbc6fd6ff925a3e. - Multi-monitor window placement and sizing robustness (treeland): kept windows visible and correctly positioned when outputs change or are removed; surfaces migrate to the primary output with correct geometry adjustments. Commits: 3e520c5b30d294eebf545c386e24290957394352; 0fcba8d63bfeaf9b042b847f51bc6f7ef5777f56; d1ae2372bd2074f71cba0651d7b3d5a06e7ecb05. - Drag-and-drop workspace crash prevention during move (treeland): short-circuited on beginMoveRows failures to prevent crashes during workspace swaps. Commit: 2a0580256e54ea93bf8489d1cd9d3e7063eb00ec. - Typo corrections and UI consistency improvements in QML; animation timing alignment: corrected spelling and property references for task switching and window previews; aligned animation durations to root object for consistent visuals. Commits: f4bd757ce4c95fbbf87ba3769c983e86156ff264; e6cf67c06cad2ffc846474e57056c75ac786bd97. - Waylib multi-display stability fixes: prevented a empty primary output on removal and avoided crashes when unplugging screens in multi-screen mode. Commits: 75a216244e5b9b6758a19c298541e11d6f7f28a5; d7f191dba2d3280212decf925de5b8dbd711ff03.
