Using xrestop

The xrestop tool uses the X11 Resource extension to provide statistics. Similarly to top, xrestop provides data on the server-side resources used by each connected X11 client. The tool allows you to find out which application's X resource usage or leakage causes X server memory usage to increase inappropriately.
