Worked on stabilizing Windows tray label updates within the shadps4-emu/ext-SDL repository, focusing on improving UI reliability for SDL extensions. Addressed a bug in the SDL_SetTrayEntryLabel function by correcting the fByPosition parameter, ensuring tray items are identified by their ID rather than position during label updates. This change prevented misidentification of tray items, reducing potential inconsistencies in the Windows user interface. The work involved C programming and direct use of the Windows API, with careful attention to code maintainability and traceability. Delivered a targeted bug fix that supports future audits and simplifies debugging for ongoing development and maintenance.
