Worked on stabilizing graphics performance for ARM devices in the AvaloniaUI/angle repository, focusing on mitigating performance issues related to the Vulkan-based graphics pipeline. Addressed a critical bug by temporarily disabling the Vulkan pipeline on ARM platforms, preventing user-facing performance degradation while deeper root-cause analysis is conducted. This approach maintained application stability and responsiveness during the investigation period. Utilized expertise in graphics programming, performance optimization, and C++ to implement and validate the mitigation. The work ensured that users experienced consistent performance on ARM devices, while providing a safe environment for ongoing debugging and future improvements to the graphics subsystem.
