January 2026 monthly summary for libsdl-org/SDL: Focused on stability and correctness in input handling by implementing a memory allocation type-safety fix for keyboard and mouse ID arrays. This change corrects type casting in allocations for SDL_GetMice() and SDL_GetKeyboards(), improving memory management, API safety, and overall reliability.

February 2025 performance summary for shadps4-emu/ext-SDL. The Windows graphics stack on this repository was hardened to improve stability, reliability, and user experience. Key features delivered and bugs fixed focused on Windows cursor handling and bitmap/graphics execution paths, driving tangible business value in end-user experience and maintenance costs. Key features delivered / major bug fixes: - Windows Cursor Handling Robustness and UX: stabilized cursor creation/update flows by eliminating memory/resource leaks and double-free issues; updated UI feedback by aligning the progress cursor with a proper system cursor.

Commits: 5c79f4cae19d5fdd8a1e132155568aac3c8c2b3e; 31f9cb4806c1972882b933f676e550366a34050f. Overall impact and accomplishments: - Increased stability and predictability of Windows rendering paths, with fewer leaks, crashes, and misbehavior in cursor and bitmap/graphics flows. - Improved power-management behavior through robust screen saver suspend handling, contributing to better resource utilization and user experience. Technologies/skills demonstrated: - Win32 API / GDI, cursor and bitmap handling, memory/resource lifecycle management, error handling, and basic concurrency considerations in graphics pipelines.

Month: 2025-01 | Focused on stabilizing cursor rendering within the SDL extension by correcting hotspot calculations. Delivered a targeted bug fix to ensure vertical hotspot Y position uses hot_y (instead of hot_x), addressing vertical misalignment when cursors are scaled across the shadps4-emu/ext-SDL repository. Key commit: 169c8d5140df522561f0f44d1490eea14e44b27b (Fix incorrect hotspot calculation for cursor positioning).
