Valve traced a SteamVR Error -203 black screen to a Vulkan ring buffer overflow

Valve traced the Error -203 black screen in the SteamVR 2.18.3 beta to an assert in SteamVR's own Vulkan renderer. A Valve developer cited two lines from the reporter's October 10 compositor log, both reading 'Vulkan transfer ring buffer overflow' at vrrenderer/vulkanrenderer.cpp line 5502, one at a transfer size of 71,100.
