This is a simple overlay showing current GPU activity. An asynchronous overlay is used, rendered by the CPU to avoid introducing any extra work on the GPU that we wish to monitor. The x11-overlay backend requires xf86-video-intel 2.21.15 or later, with SNA enabled. As it requires access to debug information, it needs to be run as root.
