The leak(s) correspond with performance degradation over time, especially on systems with relatively low amounts of VRAM (I have 256MB). User-visible symptoms include: * Performance degradation over time * Sluggish animations, such as when using Super-W and Super-S * When switching windows, window contents briefly drawn as black rectangles before being rendered correctly * Window decorations not drawn on new windows 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 pixmam memory ('Pxm mem') associated with the gtk-window-decorator 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 19 extra window handles on my system. - 4) Close the window + 4) Close the window Expected results: Per xrestop, the number of window handles goes down when you close the window. (Are some of the handles are related to window-open animation? In that case I'd expect them to be disposed of when the animation is complete) Actual results: Per xrestop, the number of window handles remains the same when you close the window. I also observed that the total pixmap memory used by gtk-window- decorator steadily climbs over time. While closing a window does appear to release some pixmap memory, it does not seem to release all of it. Performace on my system with 256MB VRAM got really bad when the number of window handles in gtk-window-decorator climbed above 7000 and the total pixmap memory used by gtk-window-decorator was about 75MB. Killing + restarting gtk-window-decorator temporarily solves the problem. - xrestop output: xrestop - Display: localhost - Monitoring 32 clients.
