Worked on the Godot engine’s godotengine/godot repository, focusing on improving the Editor Visual Profiler’s stability and accuracy. Addressed a visual bug where reference frame lines were rendered outside the profiling graph’s bounds, which could lead to misinterpretation of CPU and GPU metrics. The solution involved refining the C++ rendering logic to ensure all reference lines remained strictly within the graph container, enhancing both the clarity and usability of performance data. Applied skills in C++ programming, game development, and visual debugging to deliver a targeted, low-risk fix that maintained the profiler UI’s stability without introducing new features or regressions.
