After such a long period of time you are likely experiencing multiple leaks from multiple apps. You would need to do exhaustive testing with a single app over a long period to narrow down which is to blame. It's probably not worth it, but maybe you can identify the most problematic apps given more time...
Regardless, it sounds like the source of your leaks is not marco or Xorg. So I will mark those tasks as Invalid. But that doesn't mean this issue is closed. Feel free to add any apps you suspect to the top of this bug. ** Changed in: marco (Ubuntu) Status: Incomplete => Invalid ** Changed in: xorg-server (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/marco/+bug/1884850/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
