MangoHud v0.8.4 has been released, addressing several issues primarily related to Vulkan layer functionality and DirectX API detection. A significant fix resolves problems with Steam Overlay coexistence, which previously impacted stability when used with MangoHud due to "Vulkan layer procaddr/trampolining issues." This should improve the user experience for those utilizing both tools, especially in Steam games on Linux. The update also includes fixes for DirectX API reporting, ensuring dx_api correctly displays versions for DX9/11 and now includes support for DX3-7. Further Vulkan-specific changes involve fixing loader procaddr forwarding and exporting a Vulkan layer negotiation entrypoint, contributing to overall stability and compatibility within the Vulkan rendering pipeline.
