February 2025 highlights for gfxreconstruct (facebook/gfxreconstruct): delivered two high-impact stability fixes. - Vulkan replay memory size handling bug: Prevented segmentation faults during replay by overriding memory requirement functions to ensure memory sizes are respected when replay sizes exceed capture sizes in Vulkan allocators. (Commit 67f43c5a71ca31f828d06512f0956555b42f3fd7) - Android multi-window stability during surface recreation: Fixed release of native windows and synchronization during surface recreation to improve stability of multi-window Android functionality. (Commit eb511f54419f1f270409022c0aefa09407edcce5) Impact: significantly improved replay fidelity and runtime stability, reduced crash risk in Vulkan replay paths, and enhanced reliability of Android multi-window workflows. Technologies/skills demonstrated: Vulkan memory management, rebind allocator adjustments, native window lifecycle handling, and cross-platform synchronization."
