In April 2026, Zmaster Adsl focused on enhancing mouse input reliability for SDL-based applications by addressing a scrolling issue in the libsdl-org/SDL repository. Working with Objective-C and leveraging the Cocoa Framework and Game Controller API, Zmaster replaced unreliable GCMouse scroll events with AppKit-based scrolling, refining the interpretation of scroll deltas for consistent behavior across macOS devices. The solution also included a workaround for a CGMouse API bug that previously affected scroll event detection. This targeted fix improved cross-application compatibility and input stability, demonstrating a deep understanding of macOS development and careful attention to platform-specific input handling challenges.
