Thanks for the bug report. Memory leaks in the Xorg process are usually the fault of an application. Because in X11 the server owns the resources created by applications, and any leaks will appear in the server process 'Xorg'.
To help track down any offending applications, please run this command while the leak is happening: xrestop and it will show the applications causing the most memory usage in Xorg. ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1930641 Title: memory leak in xorg-server 2:1.20.9-2ubuntu1.2~20.04.2 Status in xorg-server package in Ubuntu: Incomplete Bug description: Progressive memory leak in Xorg.
