vulkan_init creates vk->hdr.ubo whenever the build has VULKAN_HDR_SWAPCHAIN,
but vulkan_free destroyed it only when the context reported HDR support,
which this console's surface never does. One 256-byte host-visible buffer
leaked each video init, two per core reload: the two direct-memory mappings a
reload that Profile 9 left unidentified. The patch count goes from 202 to 203
for this one block.
Title 9a84b116, four reloads of Melee: every reload returns to 180 live
mappings and memory:152 (evidence/dolphin-p9-reload-flat).
