Intel Is Working On A Vulkan Overlay Layer, Inspired By Gallium3D HUD

Aside from some out-of-tree experiments last year by one of Valve's developers on a RADV Vulkan HUD of similar nature to the popular Gallium HUD option, it turns out an Intel developer has recently been working on a Vulkan overlay layer to provide 'Gallium HUD' inspired information. From a report: Lionel Landwerlin is the open-source Intel developer that has begun working on this Intel Vulkan driver 'heads-up display' implemented as a Vulkan overlay layer. The code is intended to provide Vulkan swapchain information and various statistics of use to Vulkan driver developers and game developers. The code is under a merge request for Mesa but is considered experimental at this point. Particularly for multi-threaded Vulkan programs it may end up crashing in its current form.
