#2450: Xorg resource leakage
             Reporter:  raimund  |                     Type:  defect
               Status:  new      |                 Priority:  normal
            Component:  FFmpeg   |                  Version:  1.1.4

 Summary of the bug:

 ffmpeg increases virtual memory of Xorg server.

 How to reproduce:
 Operating system: CentOS release 6.2 (Final)
 ffmpeg releases: 1.1.4, 1.2
 configuration: --disable-yasm --enable-gpl --enable-x11grab --enable-
 version3 --enable-libvo-aacenc

 % ffmpeg -f x11grab -s cif -r 25 -i :0.0 /tmp/out.mpg

 and monitor X11 client resources by
 % xrestop

 You will find an <unknown> client constantly increasing X11 server memory.
 Batch usage of xrestop indicates leak in category "cursors".
 (Maybe ticket #1738 introduced it?)

 Bug does _not_ appear for releases 0.11.3 and 1.0.6!
