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.

Xorg server uses unacceptably large amounts of memory (and keep

Bug description:
Description: Xorg server uses unacceptably large amounts of memory
(and keep growing)
Ever since I upgraded to Ubuntu 20.04 (with fresh install) on my
laptop (Lenovo T450s, Intel Core i5-5200U, Intel HD5500 graphics), I
have been troubled by the way Xorg process uses memory.
Here is an example of memory usage of Xorg as a function of time. I
rebooted the laptop on June 17:

The filename indicates the date the "ps fuxa" command was run.
Contrast this against the memory usage of another Xorg process run for XPRA:

My desktop usage pattern:
* MATE desktop
* 4-desktop setting (standard default MATE when shipped)
* GNUCASH
* about 3 windows of terminal (each about 5-10 tabs)
* XPRA running Firefox web browser (to isolate web browser pixmap memory
usage, if that was the culprit)
* LibreOffice (several windows open at any time)
* using "redshift" to change the desktop color to red at night
I have never seen this before using Ubuntu 20.04 on this machine.
Before, when I was running Debian 8, I could run this machine for months
literally without Xorg memory bloating rapidly like this (but then I was using
xfce instead of MATE).
I viewed the output of xrestop, the pixmap memory usage is dominated by marco
and wnck-applet:

In the previous boot (starting May 27 and ending June 17), the XOrg
memory consumption grew to 1.7 GB total.
I don't know exactly which software is responsible to cause this
problem, so I started out with xorg server.
