My gtk-window-decorator regularly climbs to 500 MB and I end up swapping
a lot with other programs running. Alt-Tab between windows increases the
use. Basically, I get around 1 MB added to the total memory used by gtk-
window-decorator for each time I Alt-Tab between windows (as observed by
System Monitor's). No end in sight in terms of chomping more (leaking
more?) memory.

Title:
  Runaway memory usage in gtk-window-decorator

Status in Unity:
  Fix Released
Status in compiz package in Ubuntu:
  Invalid
Status in unity package in Ubuntu:
  Fix Released

Bug description:
  I've just been in a situation where gtk-window-decorator has consumed almost all of my memory via i915 gem objects:
  └─(16:33:%)── sudo cat /sys/kernel/debug/dri/0/i915_gem_objects                                                                                                                                                          ──(Wed,Aug17)─┘

  Killing compiz dropped that object total by ~1GB; killing gtk-window-
  decorator dropped it back down to ~300MB.

  Perhaps gtk-window-decorator or compiz is leaking textures?
