Worked on enhancing the stability and memory management of the Vulkan backend in the google/filament repository, focusing on long-running workloads. Addressed a critical memory leak in the Vulkan fence pool by ensuring proper deletion of synchronization objects, using C++ and the Vulkan API. The solution involved casting sync objects to their derived type before deletion to avoid undefined behavior caused by a non-virtual destructor, thereby improving cross-platform reliability. Documented the destructor policy to guide future maintenance without incurring vtable overhead. This work resulted in reduced memory growth and more predictable behavior for Vulkan-based applications, emphasizing robust memory management practices.
