During two months on the shadps4-emu/ext-SDL repository, Thouravi focused on stabilizing Windows graphics and cursor handling using C and the Win32 API. He addressed three complex bugs, including correcting cursor hotspot calculations to eliminate rendering misalignment and fixing memory and resource leaks in cursor creation flows. His work improved error handling and resource management, notably by resolving double-free issues and refining bitmap offset calculations for more reliable graphics execution. Thouravi’s contributions enhanced the predictability and stability of cross-platform rendering paths, reduced maintenance overhead, and improved user experience, demonstrating depth in low-level programming, memory management, and Windows development.

Feb 1, 2025February 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. Related commits include ca9a044b3efdd62fef5fb1fdb90e703453ccc004; 7aba6c4c735a072ee019df94c5fda9057f6dbcd7; a51316890218c89fa3350178cbe2c79146a01d2e; ed0a03e9b5f35da03cdc1e0941b2bd770c8a7ef9; 057c3602e9ef5564a7da4f35f9d28a8e15af9c20. - Windows Bitmap and System Execution Stability: corrected DIB to BMP offset calculation and added error handling for thread execution state during screen saver suspend to improve reliability of Windows graphics and power management flows. 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.

Jan 1, 2025Month: 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).
