Title:
  Pixmap memory leak in gtk-window-decorator

Status in Compiz Core:
  Fix Released
Status in compiz package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: compiz

  My Xorg process memory usage continues growing over time. Here it is
  after a few hours:

  1498 root      20   0  426m 253m  20m S   12  6.4  12:10.87 Xorg

  I have used xrestop to see where the memory is going. Here is the
  output:

  xrestop - Display: :0.0
            Monitoring 42 clients. XErrors: 2
            Pixmaps:  215589K total, Other:     105K total, All:  215694K total

  Is there anything else I need to do ?
