Over two months, contributed to mozilla/gecko-dev by building and refining HDR support and video playback observability for Linux/Wayland environments. Focused on stabilizing rendering pipelines, improving DMABuf handling, and implementing asynchronous HDR monitor detection using C++ and GTK. Enhanced system reliability by introducing GL fence-based synchronization, reorganizing screen retrieval, and expanding logging for color space and HDR metadata. Addressed cross-driver compatibility and reduced UI glitches by refining event handling and lifecycle management. The work demonstrated depth in low-level graphics programming, concurrency, and system configuration, resulting in smoother HDR experiences and improved maintainability across diverse hardware and compositor setups.
