Test case:
1. Install xrestop (sudo apt-get install xrestop)
2. Run xrestop and look for the gtk-window-decorator row
3. Note the values for "Pxms" and "Pxm mem".
4. Resize a window rapidly.
Expected: No significant change in Pxm metrics.
Observed: Hundreds of pixmaps leaked and Pxm mem grows by several megabytes per second.
