Worked on stabilizing the Zed editor’s startup process on X11 by addressing compatibility issues with older XInput versions in the zed-industries/zed repository. Focused on Linux development and system programming using Rust, the solution involved negotiating the XInput version at runtime and conditionally enabling gesture-related event masks only when supported. This approach prevented crashes on X11 servers lacking gesture mask support while maintaining full input and gesture functionality on newer systems. The implementation introduced a supports_xinput_gestures flag, updated event mask assembly, and enhanced logging and tests, ensuring robust UI development and improved reliability across diverse remote and X11-forwarded environments.
