syslog gdm-x-session "your system is too slow" as desktop GUI slows down and eventually stops

[Ryan Erwin]

After ~72 hours, my Gnome desktop will be very slow.

In syslog I noticed that I get a bunch of these messages as the system slows down:

/usr/lib/gdm3/gdm-x-session[13460]: (EE) client bug: timer event6 debounce short: scheduled expiry is in the past (-30ms), your system is too slow
