Worked on the wolfpld/tracy repository to address a macOS-specific UI issue by fixing a 2x DPI scaling problem when using ImGui 1.92. The solution involved adjusting the DPI scaling logic to honor user-defined scale settings, ensuring consistent and readable interfaces on HiDPI displays. This targeted bug fix required a strong understanding of C++ development, ImGui integration, and cross-platform UI challenges. The approach minimized code changes while maintaining clarity for future maintenance. By resolving user-reported scaling issues, the work improved overall UI usability and reduced support overhead, demonstrating careful attention to both technical detail and user experience in UI development.
