    • Tested only on Ubuntu 9.04, 10.10, 11.04; 32 bits

      Running the application attached, we can see the process running ever more low, and the usage of memory usage increasing.
      The application makes several paints using QTimer for the updates.

      When this poor performance we see in "sudo gnome-system-monitor" that the Xorg process is using almost all CPU.
      Killing the application and restating again, returns to initial performance.
