mesa-overlay with control arg fails to setup socket properly when multiple adapters launched. First adapter listens to socket, blocking all remaining adapters. This is a common occurrence with games using lauchers where the launcher is also a vulkan app. Fixed by deferring socket listening to first frame rendered, which should be the game.
