This shouldn't be a warning either, not even an info message, since
many systems are apparently affected and this doesn't seem to have
any consequence. So perhaps this is normal, after all. I'm wondering

which mentions that this is due to the compositor. But I currently
don't use a compositor on any of my machines.

/var/log/Xorg.0.log has
(EE) event2  - Logitech USB Keyboard: client bug: event processing lagging

So my keyboard is faster than my CPU, and it is an error, not even a warning?
