I see the Window handle leak also in Ubuntu 14.10. With newer kernel & HW, it once cause Compiz to be OOM-killed (see bug 1415926).

Status in Compiz: Triaged Status in Compiz 0.9.8 series: Won't Fix Status in compiz package in Ubuntu: Triaged Bug description: Compiz leaks window handles when closing windows, according to xrestop. To reproduce: 1) install xrestop ("apt-get install xrestop") 2) In a terminal, launch xrestop. Keep it running, and observe the number of 'Wins' and amount of pixmap memory ('Pxm mem') associated with the Compiz process 3) Open a new terminal (or any other) window. Observe that the number of windows had gone up by some amount. Opening a terminal window reliably results in exactly 3 extra window handles for the Compiz on my system. 4) Close the window Expected results: After closing the terminal window, the number of window handles held by the compiz process returns to the level observed in step 2 Actual results: The number of window handles does not decrease; Compiz retains the window handles for the closed window. It's reliably 3 window handles for each terminal window on my system. I haven't checked other window types (dialogs, etc). The above steps also produce a 1KB leak of pixmap memory on my system. I am not sure if this is related.
