In December 2025, this developer enhanced X11 event handling in both the godotengine/godot and Redot-Engine/redot-engine repositories to address input delay issues in GUI-heavy workflows. By lowering the X11 event thread timeout and introducing customizable timeout parameters, they enabled faster event polling and more responsive user interactions. Their work, implemented in C++ and leveraging event-driven programming and system programming skills, standardized timeout handling across both engines for consistent performance. The changes reduced input latency and improved user experience, while also establishing a scalable foundation for future performance optimization in X11 event processing. No bugs were fixed during this period.
