Worked on the jellyfin/jellyfin-desktop repository to address a critical video playback issue affecting Wayland users. Focused on desktop application development using C++ and SDL, the developer implemented a targeted fix that applied a transparent window flag, ensuring video layers rendered correctly and resolving the persistent black window problem. This solution stabilized cross-platform playback on Wayland, reducing user-reported incidents and support overhead. The work demonstrated a strong understanding of Linux windowing systems, with careful, minimal changes and thorough testing across popular Wayland environments. The contribution improved reliability and user experience for video playback without introducing unnecessary complexity to the codebase.
