Public bug reported:

gtk-window-decorator leaks a pixmap and pixmap memory for each window
that's opened. This is reproducible on both 13.10 and 14.04. As a
result, gtk-window-decorator pixmap memory climbs (apparently) unbounded
during normal usage. After several hours of heavy usage a machine can
start to become unresponsive.

To reproduce:
1) Login; launch a terminal (ctrl-shift-t)
2) Run xrestop in the terminal and observe the number of pixmaps (pxms) and amount of pixmap memory in use (pxm mem) for the gtk-window-decorator process
3) Open a new terminal window (ctrl-shift-n). Observe that the number of pixmaps goes up and the amount of pixmap memory goes up
4) Close the terminal window from step 3. Observe the number of pixmaps and amount of pixmap memory for the g-w-d process

Expected results:
After closing the terminal window, g-w-d pixmap memory should return to the original value observed in step 2

Actual results:
The number of pixmaps in the g-w-d process is 1 higher than the value observed in step #2, and the amount of pixmap memory in use grows. The leak is about 200K per terminal window, on my machine.

This is 100% reproducible on both a machine with NVIDIA graphics running
13.10 and a machine with Intel graphics running 14.04.


Attached is data gtk-window-decorator data copied from xrestop while repeatedly opening + closing a terminal window.
