I have the same problem. After some time of use (some hours to some days, after some suspend/resume cycles) compiz and Xorg both reach around 500MB used RAM each. "compiz --replace" frees up compiz' used memory, but Xorg stays the same.
I had the same problem since forever (starting with natty and Nvidia 295 drivers) and now saucy (319-updates). If I had to guess this seems to be more of a nvidia/Xorg problem, than a compiz problem. Current system: - Ubuntu 13.10, stock kernel (3.11.0-12-generic), proprietary Nvidia drivers (319-updates) on a NVS 5200M laptop GPU -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/870042 Title: Memory leak in compiz (and maybe Xorg) To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/870042/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
