Contributed to the bevyengine/bevy repository by developing a Wayland fullscreen fallback mechanism, enhancing startup compatibility for exclusive fullscreen applications on Linux. Leveraging Rust and cross-platform development skills, the work introduced a system that detects unavailable monitors and gracefully switches to borderless fullscreen, accompanied by a robust warning and fallback process. This approach improved user experience and reliability for Wayland users, particularly on Fedora 43 with COSMIC, and addressed platform parity concerns for fullscreen workflows. The implementation focused on UI/UX design and system programming, ensuring that Bevy’s Linux user base benefits from smoother application launches and reduced startup failures.
