| 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. |
