Worked on stabilizing DPI handling for conhost within the microsoft/terminal repository, focusing on improving user experience across high-DPI displays. Addressed a critical bug by updating the DPI scaling logic to use the size provided by WM_GETDPISCALEDSIZE, rather than relying on the current window size, ensuring that pending size changes were properly respected during DPI transitions. This targeted patch reduced visual glitches and maintained consistent text fitting as DPI settings changed. The work demonstrated expertise in C and C++ as well as deep familiarity with Windows API, emphasizing careful debugging and low-risk remediation to enhance UI reliability and stability.
