Worked on OSWorld’s X server integration, focusing on backend development and system programming using Python. Addressed a resource leak in display connections by implementing context-managed display handling, ensuring that resources were properly released after use. This technical approach reduced memory usage and improved the stability of screen capture and window management, particularly during long-running sessions. The solution involved explicit cleanup paths, which enhanced code maintainability and facilitated future refactoring. All changes were delivered in the xlang-ai/OSWorld repository, resulting in fewer leak-related failures and a more reliable operational environment for both end users and downstream systems. No new features were added.
